Irrlicht i18n (Unicode, FreeType, etc.)

Postby Nalin » Fri Feb 12, 2010 1:52 pm

What is this?
These are a collection of classes I have written that provide Irrlicht the ability to handle/read/write/draw unicode text. Everything here is based off the abilities of the ustring class. The ustring class, CGUITTFont class, and the CStringTable class are all licensed under the zlib license, the same license that Irrlicht uses.

ustring
Download: irrUString.h
ustring is a UTF-16 string class. It can convert to/from UTF-8 and UTF-32. Using an iterator, one can gain access to each unicode character in the string. This is the base class used by everything else. It is heavily documented in doxygen format. It also supports C++0x move semantics for users of Visual C++ 2010 and GCC (when using -std=c++0x). This provides a performance improvement when dealing with a lot of temporary copies (ie, chaining multiple strings together with +).

To use everything else in this post, you must place this file in Irrlicht's include directory and add to irrlicht.h:
#include "irrUString.h"

XML reading/writing
Download: CXMLWriterUTF8.zip
Download: xml_io.patch
-- svn trunk
-- 1.7.2
These are tweaks to the XML reading/writing system. It enables Irrlicht to correctly read any type of UTF encoded XML file and write UTF-8 encoded files. As reading files is built into Irrlicht, a patch for CXMLReaderImpl.h is required. As Irrlicht uses CXMLWriter when serializing elements, a patch for CFileSystem.cpp is required to use the new CXMLWriterUTF8 class.

Add CXMLWriterUTF8.h and CXMLWriterUTF8.cpp to Irrlicht's source directory, add the files to the Irrlicht project, and apply the patch to gain access to this feature.

Multi-byte font rendering
Download: CGUITTFont.zip
-- svn trunk
-- 1.7.2
Requires: FreeType 2
To render multi-byte unicode, CGUITTFont was created. This requires FreeType 2 to work and a font that contains the glyphs you wish to render. The class will return a gui::IGUIFont that you can then bind to Irrlicht's GUI for rendering. The class has full doxygen documentation built-in.

Add CGUITTFont.h and CGUITTFont.cpp to your project to gain access to this ability. Remember, you must be using FreeType 2 in order to draw TrueType fonts.

Multi-language string tables
Download: CStringTable.zip
To help facilitate internationalization, the string table class allows you to change the language of your application just by loading in a specially designed XML file.

Add CStringTable.h and CStringTable.cpp to your project to gain access to this ability.

How does this all work?
Irrlicht makes heavy use of wchar_t, which is a data type that varies in size depending on your platform (16 bits on Windows, 32 bits on Linux, etc.) ustring has the ability to convert to/from a stringw holding its proper, platform specific unicode string (UTF-16 in Windows, UTF-32 in Linux, etc.) You read your data into a ustring and convert it to a stringw when you need to pass it through Irrlicht (like, for example, drawing it on the screen), converting it back to a ustring when it reaches its destination. CGUITTFont will convert the stringw back into a ustring before it draws the text. This allows us to have basic internationalization support without gutting Irrlicht.

How do I convert my ustring to other strings?
cpp Code: Select all
 
ustring test("This is a test \xEF\xBF\xBD");
stringc test_char = test.toUTF8_s();
stringw test_wchar = test.toWCHAR_s();
io::path test_path = test.toPATH_s();
 


How do I use a ustring iterator?
cpp Code: Select all
 
ustring test("This is a test \xEF\xBF\xBD");
test += (uchar32_t)0x10400;
std::cout << "test.size(): " << test.size() << std::endl;
std::cout << "test.size_raw(): " << test.size_raw() << std::endl;
 
ustring::iterator end = test.end();
for (ustring::iterator i = test.begin(); i != end; ++i)
{
  uchar32_t character = *i;
  std::cout << "character: " << character << std::endl;
}
 
// Yes, we can directly output our ustring to std::cout.
std::cout << test << std::endl;
 
// The iterator is STL compatible, so we can use C++0x and the STL to increment each character by 1.
std::for_each(test.begin(), test.end(), [](ustring::access& c) { ++c; });
 
// And we can output to std::wcout too.
std::wcout << test << std::wendl;
 


How do I use CGUITTFont?
cpp Code: Select all
 
// Get a 14 pixel high code2001 font.
gui::CGUITTFont* tt_font = gui::CGUITTFont::createTTFont(device->getGUIEnvironment(), "code2001.ttf", 14);
 
// Set the font.
gui::IGUIEnvironment* env = device->getGUIEnvironment();
gui::IGUISkin* skin = env->getSkin();
skin->setFont(tt_font);
 
...
 
tt_font->drop();
 


How do string tables work?
A string table will hold all the translated strings for a given language. Your project should have a string table for each language you want to support.

cpp Code: Select all
// A string table can be loaded using the loadStringTable() function in the irr::st namespace.
st::CStringTable* stringtable = st::loadStringTable("example.irrst", device->getFileSystem());
 
// Then we can set it to be the active string table.
st::setActiveStringTable(st);

cpp Code: Select all
// Alternatively, you can use the CStringTableManager class.
CStringTableManager mgr;
 
// The CStringTableManager class can load all .irrst files in a directory.
mgr.loadDirectory("translations", device->getFileSystem());
 
// We can then set the active table by the language of the string table.
mgr.setActiveStringTable("English");

cpp Code: Select all
// We can get a string directly from a string table.
st::CStringTable* english = st::loadStringTable("english.irrst", device->getFileSystem());
 
// Both getTranslation and _T will return the string associated with the given ID.
core::ustring username = english->getTranslation("Username");
core::ustring password = english->_T("Password");
 
// Or, we can set it as the active string table...
st::setActiveStringTable(english);
 
// ...and use the st::_T() function to grab a string from it.
core::ustring nickname = st::_T("Nickname");

cpp Code: Select all
// The same thing works with the CStringTableManager.
CStringTableManager mgr;
mgr.loadDirectory("translations");
mgr.setActiveStringTable("Español");
core::ustring nickname = st::_T("Nickname");
...
gui::IGUIStaticText* passtext = env->addStaticText(st::_T("Password").toWCHAR_s().c_str(), core::recti(200, 180, 200 + 200, 180 + 20), false, false, window, GUI_LOGIN_PASSWORD, false);

cpp Code: Select all
// We can also manipulate parameters in the strings.
// We will be using this string:
//     Hello, {{%1}}!  How are you?
// In our Spanish language file, it is translated as this:
//     ¡Hola, {{%1}}!  ¿Cómo estás?
// Assume that the currently active string table is the Spanish table.
const core::ustring nick_name("Bob");
...
// This will return:
//     ¡Hola, Bob!  ¿Cómo estás?
core::ustring greeting = st::_T("Hello, {{%1}}!  How are you?").param(nick_name);
...
// By default, parameters are in the format:
//   {{%1}}, {{%2}}, ...
// But that can be changed:
st::CStringTable* english = st::loadStringTable("english.irrst", device->getFileSystem());
 
// This sets the parameter format to the following:
//     [#1], [#2], ...
english->setParameterFormat("[#", "]");

The CStringTable.zip download contains a sample .irrst file that illustrates how to assemble the file. But, as a small example:

cpp Code: Select all
<?xml version="1.0"?>
<irr_stringtable>
        <language value="Español" />
        <entry>
                <id>Nickname</id>
                <translation>Apodo</translation>
        </entry>
        <entry id="Username"><![CDATA[<Nombre de usuario>]]></entry>
        <entry id="Password">Contraseña</entry>
        <s id="Language">Idioma</s>
</irr_stringtable>


What's next?
I'm not sure. Care to suggest something?

---

I have a keyboard that has non-ASCII characters. When I type into a text box in Irrlicht, it doesn't show the proper character! Why? (ALSO: Why can't a paste unicode text into Irrlicht?)
These patches don't solve this issue. If you want to be able to input unicode characters into Irrlicht, please take a look at MadHyde's patches:
http://irrlicht.sourceforge.net/phpBB2/viewtopic.php?p=220810#220810

Please note that as of the time of this post edit, Linux support in MadHyde's patches is incomplete.

I dare say this is most likely the best current project open to this community, maybe only in competition with Spark, xEffects and CG integration.

Sorry about that. I just recently switched hosts and wouldn't you know, those files were the one thing I forgot to switch over. :x

Anyways, it is fixed now. You just have to wait for the DNS to update.

I've uploaded a new version of ustring and CGUITTFont. Download links are in the OP.

--------------------------------------------------

Changes in ustring:
  • Renamed the class to ustring16, added custom allocators back in, and added a ustring typedef.
  • Renamed all the byte order mark constants in the unicode namespace to better convey their functions.
  • Added endianness conversion features.
  • The class checks for byte order marks when you construct a new string.
  • Ability to add byte order marks and specify endianness when using the string conversion functions.
  • Various bugs fixed.
The big new features are the byte order marks and the endianness features. When you construct a new string, it will check to see if a byte order mark is present. If one is, it will correctly construct the string, taking into account the endianness specified by the mark. The byte order mark will NOT be saved into the string, however.

The string now saves its EUTF_ENCODE type. The encoding of the string can be retrieved via the getEncoding() member function. Currently, the only valid return values you should get are EUTFE_UTF16_LE and EUTFE_UTF16_BE.

I added a new enum, EUTF_ENDIAN. The getEndianness() member function will also return the endianness of the ustring.

I also updated all the unicode conversion routines (the toUTF8, toUTF16, toUTF32 member functions.) You can choose whether or not the function adds the appropriate byte order mark to the output string by passing true to the addBOM argument. Also, for the toUTF16 and toUTF32 functions, you can specify which endianness you wish the resulting string to have: EUTFEE_NATIVE, EUTFEE_LITTLE, or EUTFEE_BIG.

These new changes make it very easy to read/write proper Unicode formatted files complete with appropriate byte order marks. The class will take care of all the necessary endian conversions for you.
Code: Select all
// Passing true tells the class to include the byte order mark.
core::array<uchar8_t> utf8 = mystring.toUTF8(true);

io::IWriteFile* f = device->getFileSystem()->createAndWriteFile("mysettings.txt");
f->write(utf8.pointer(), utf8.size());
f->drop();

--------------------------------------------------

Changes in CGUITTFont:
  • If the engine tries to draw a character that doesn't exist in the font, it will first try to draw the Unicode replacement character before drawing a blank space.

The CGUITTFont change requires the updated version of ustring.

Hi Nalin
I have change code fix problem and i compiled success but i cannot run because it is crash.
From code
// Get a 14 pixel high code2001 font.
// If the third parameter is true, the size is in pixels. If false, it is in font points.
gui::CGUITTFont* tt_font = gui::CGUITTFont::createTTFont(device->getGUIEnvironment(), "tahoma.ttf", 14, true);

// Set the font.
gui::IGUIEnvironment* env = device->getGUIEnvironment();
gui::IGUISkin* skin = env->getSkin();
skin->setFont(tt_font);

...

tt_font->drop();

change code
// Get a 14 pixel high code2001 font.
// If the third parameter is true, the size is in pixels. If false, it is in font points.
gui::CGUITTFont* tt_font = tt_font->createTTFont(device->getGUIEnvironment(), "tahoma.ttf", 14, true);

// Set the font.
gui::IGUIEnvironment* env = device->getGUIEnvironment();
gui::IGUISkin* skin = env->getSkin();
skin->setFont(tt_font);

...

tt_font->drop();

This is fix problem but it is crash when i run app

Your issue is that you removed the "static" keyword from the createTTFont() function. That "static" keyword is very important. If you remove it, it changes the whole meaning of the function and the way the class operates. Basically, it will completely break it. Instead of changing it, we should address your first issue: the linker error.

Try adding #include <CGUITTFont.h> to the top of your source file. It doesn't seem that you added it, and it is very important that you do.

EDIT: Also, are you adding CGUITTFont.h/cpp to your project, or to the Irrlicht library directly? You should be adding it to your project, not to the Irrlicht library.

Hi,
thanks for sharing your usefull classes :wink:

However I got a little compiler error:
line 1912: irrUString.h incomplete universal character name \u16

The concerned line is:
Code: Select all
ustring& trim(const ustring& whitespace = " \u16\n\r") { ...

You have an older version of irrUString.h. That was fixed in one of the recent versions. Just download it again from the OP.

Yes, I used directly the guifont zip file which doesn't contain the newest version. I got now the other good file.

So, firstly I just put irrUString in my Irrlicht 1.7.1 include directory and added the line #include "irrUString.h" after all includes in the irrlicht.h file.

The compiler doesn't like it.
Did you use irrlicht 1.7.1? Which version of gcc is working with it? I'm using DevC++ which doesn't use the lastest gcc compiler.

Here is the compiler output:
