C and C++ headers, C# and Python classes, Rust files and Go package for icon fonts Font Awesome, Fork Awesome, Google Material Design, Pictogrammers Material Design icons, Kenney game icons, Fontaudio, Codicons and Lucide.

A set of header files and classes for using icon fonts in C, C++, C#, Python, Rust and Go, along with the python generator used to create the files.

Each header 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 the python script can be used 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.

Font Awesome 5 and 6 split the different styles of icons into different font files with identical codepoints for light, regular and solid styles, and a different set of codepoints for brands. We have put the brands into a separate header file.

Download the Font Awesome Pro Web package from fontawesome.com. To generate the headers, drop icons.yml in the same directory as GenerateIconFontCppHeaders.py before running the script. The file icons.yml is under ..\fontawesome-pro-n.n.n-web\metadata\icons.yml where n.n.n is the version number.

Icon files:

• ..\fontawesome-pro-n.n.n-web\metadata\icons.yml
• ..\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

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.

Voxel editor and 6 degree of freedom FPS game with editable environments. The voxel editor's UI uses Dear ImGui with Font Awesome icon fonts.
