A common pattern is to merge the icon font within your main font, so you can refer to the icons directly from your strings without having to change fonts back and forth. A common pattern is to merge the icon font within your main font, so you can embed icons directly from your strings without
To refer to the icon from your C++ code, you can use headers files created by Juliette Foucaut, at https://github.com/juliettef/IconFontCppHeaders having to change fonts back and forth.
See Links below for other icons fonts and related tools.
To refer to the icon UTF-8 codepoints from your C++ code, you may use those headers files created by Juliette Foucaut:
https://github.com/juliettef/IconFontCppHeaders
The C++11 version of those files uses the u8"" utf-8 encoding syntax + \u
#define ICON_FA_SEARCH u8"\uf002"
The pre-C++11 version has the values directly encoded as utf-8:
#define ICON_FA_SEARCH "\xEF\x80\x82"
Example:
// Merge icons into default tool font // Merge icons into default tool font
#include "IconsFontAwesome.h" #include "IconsFontAwesome.h"

FREETYPE RASTERIZER, SMALL FONT SIZES
---------------------------------------
Dear Imgui uses stb_truetype.h to rasterize fonts (with optional oversampling).
This technique and implementation are not ideal for fonts rendered at _small sizes_, which may appear a little blurry.
There is an implementation of the ImFontAtlas builder using FreeType that you can use:
https://github.com/ocornut/imgui_club
FreeType supports auto-hinting which tends to improve the readability of small fonts.
Note that this code currently creates textures that are unoptimally too large (could be fixed with some work)
