/*
Tool for creating Irrlicht bitmap+vector fonts,
started by Gaz Davidson in December 2006
Due to my laziness and Microsoft's unituitive API, surragate pairs and
nonspacing diacritical marks are not supported!
Linux bitmap font support added by Neil Burlock Oct 2008
Note: Xft/Freetype2 is used to render the fonts under X11. Anti-aliasing
is controlled by the system and cannot be overriden by an application,
so fonts that are rendered will be aliased or anti-aliased depending
on the system that they are created on.
acme_pjz modified the original irrlicht font tool to only write the
characters needed in a list of .po files - which saves huge amount
of space for Asian fonts.

L"------------\n\n"
L"When making bitmap and vector fonts, you should consider the potential legal "
L"issues with redistributing the fonts with your software; this tool basically "
L"copies font data and some authors might not like this!\n"
L"If you purchased fonts or they came with an application or your OS, you'll have"
L"to check the license to see what restrictions are placed on making derivative works.\n\n"
L"PD and the OFL\n"
L"--------------\n\n"
L"You'll find lots of fonts on the web listed as Public Domain, you can do what you like "
L"with these.\n"
L"Many fonts are released under the Open Font License, which is a 'viral' open source "
L"license like the GPL. It's worth reading the license here: http://scripts.sil.org/OFL\n"
L"The most important restrictions are- you must include the original font's license, you "
L"can't stop your users from using or distributing the font, the font must have a "
L"different name the original.\n\n"
L"Some free fonts can be found here- www.openfontlibrary.org\n"
L"http://savannah.nongnu.org/projects/freefont/";
const wchar_t *helptext = L"This tool creates bitmap fonts for the Irrlicht Engine\n\n"
L"First select a character encoding from the list, then choose the font, "
L"size, and whether you'd like bold, italic, antialiasing and an alpha channel. "
L"In Windows, antialiasing will be ignored for small fonts\n\n"
L"Then select a texture width and height. If the output exceeds this then more than "
L"one image will be created. You can use the scrollbar at the top of the screen to "
L"preview them. Most modern graphics cards will support up to 2048x2048, "
L"keep in mind that more images means worse performance when drawing text!\n\n"
L"If you want a vector font rather than a bitmap font, check the vector box. "
L"Vector fonts are stored in system memory while bitmap fonts are in video ram\n\n"
L"Click create to preview your font, this may take lots of time and memory "
L"when making a font with a lot of characters, please be patient!\n\n"
L"Now you're ready to give your font a name, select a format and click save.\n\n"
L"To load your font in Irrlicht, simply use env->getFont(\"Myfont.xml\");\n\n"
L"That's all, have fun :-)";
#ifdef _IRR_WINDOWS
const wchar_t *completeText = L"Font created"
#else
const wchar_t *completeText = L"Font created\n\n"
L"Please note that anti-aliasing under X11 is controlled by the system "
L"configuration, so if your system is set to use anti-aliasing, then so "
L"will any fonts you create with FontTool";
