IconFontCppHeaders
https://github.com/juliettef/IconFontCppHeaders
C and C++ headers, C# and Python classes, Rust files and Go packages for icon fonts Font Awesome, Fork Awesome, Google Material Design, Pictogrammers Material Design icons, Kenney game icons, Fontaudio, Codicons and Lucide.
A set of language files for using icon fonts in C, C++, C#, Python, Rust and Go, along with the python script we used to create the files.
Each language file contains defines for one font, with each icon code point defined as ICON_*, along with the min, max and max 16 bit code points for font loading purposes. The min excludes the ASCII characters code points. The max 16 bit is for use with libraries that only support 16 bit code points, for example Dear ImGui.
In addition you can use the python script to convert ttf font files to C and C++ headers.
Each ttf icon font file is converted to a C and C++ header file containing a single array of bytes.
To enable conversion, run the GenerateIconFontCppHeaders.py script with ttf2headerC = True.
Language Files
The following table lists all the language files for each icon font included in the IconFontCppHeaders repository.
(* For Go see also font.go and go.mod)
Icon Fonts
Font Awesome FA
Font Awesome 4
Font Awesome 5+
Font Awesome versions 5 and above split the different styles of icons into different font files with identical codepoints for regular, solid and light (pro only) styles, and a different set of codepoints for brands. We have put the brands into separate language files.

Generating Font Awesome Pro Language Files
Font Awesome Pro is a commercial product. We only support version 5. The following steps show how we generated the language files:
- Download the Font Awesome Pro 5 Web package from fontawesome.com.
- To generate the language files, drop
icons.ymlin the same directory asGenerateIconFontCppHeaders.pyand run the script. (You'll findicons.ymlunder..\fontawesome-pro-n.n.n-web\metadata\icons.ymlwheren.n.nis the version number.) - Use the language files with the following icon files:
*..\fontawesome-pro-n.n.n-web\webfonts\fa-brands-400.ttf
*..\fontawesome-pro-n.n.n-web\webfonts\fa-light-300.ttf
*..\fontawesome-pro-n.n.n-web\webfonts\fa-regular-400.ttf
*..\fontawesome-pro-n.n.n-web\webfonts\fa-solid-900.ttf
For versions 6 and above the process should be similar. You'll find an example for Font Awesome 6 Pro on @jakerieger's fork.
Example Code
Using Dear ImGui as an example UI library:
#include "IconsFontAwesome5.h"
ImGuiIO& io = ImGui::GetIO();
io.Fonts->AddFontDefault();
float baseFontSize = 13.0f; // 13.0f is the size of the default font. Change to the font size you use.
float iconFontSize = baseFontSize * 2.0f / 3.0f; // FontAwesome fonts need to have their sizes reduced by 2.0f/3.0f in order to align correctly
// merge in icons from Font Awesome
static const ImWchar icons_ranges[] = { ICON_MIN_FA, ICON_MAX_16_FA, 0 };
ImFontConfig icons_config;
icons_config.MergeMode = true;
icons_config.PixelSnapH = true;
icons_config.GlyphMinAdvanceX = iconFontSize;
io.Fonts->AddFontFromFileTTF( FONT_ICON_FILE_NAME_FAS, iconFontSize, &icons_config, icons_ranges );
// use FONT_ICON_FILE_NAME_FAR if you want regular instead of solid
// in an imgui window somewhere...
ImGui::Text( ICON_FA_PAINT_BRUSH " Paint" ); // use string literal concatenation
// outputs a paint brush icon and 'Paint' as a string.

Contributing
Thanks to everyone who has contributed to IconFontCppHeaders so far. In order to make things easier please bear in mind the following:
- I regularly update the repository. If you urgently need an update and can't run the generator yourself, raise an issue specifying the icon set(s) you need updated.
- Don't submit PRs for updating the defines (the output of the generator).
- Before submitting a PR, please raise an issue describing the problem or the enhancement you suggest. If you're able, propose an implementation.
- If you use IconFontCppHeaders and would like your project to be featured on this page, raise an issue or email me at juliette@enkisoftware.com.
