  The code in imgui.cpp embeds a copy of 'ProggyClean.ttf' that you can use without any external files.

  Fonts are rasterized in a single texture at the time of calling either of io.Fonts.GetTexDataAsAlpha8()/GetTexDataAsRGBA32()/Build().
 
+ If you want to use icons in ImGui, a good idea is to merge an icon font within your main font, and refer to icons directly in your strings.

+ All your strings needs to use UTF-8 encoding. Specifying literal in your source code using a local code page (such as CP-923 for Japanese CP-1251 for Cyrillic) will not work.
+ In C++11 you can encode a string literal in UTF-8 by using the u8"hello" syntax. Otherwise you can convert yourself to UTF-8 or load text data from file already saved as UTF-8.

  Q: How can I display and input non-Latin characters such as Chinese, Japanese, Korean, Cyrillic?
  A: When loading a font, pass custom Unicode ranges to specify the glyphs to load. 
-    All strings passed need to use UTF-8 encoding. Specifying literal in your source code using a local code page (such as CP-923 for Japanese CP-1251 for Cyrillic) will not work.
