You may want to see ImFontConfig::GlyphMinAdvanceX to make your icon look monospace to facilitate alignment.

USING ICONS
---------------------------------------
Using an icon font (such as FontAwesome: http://fontawesome.io or OpenFontIcons. https://github.com/traverseda/OpenFontIcons)
is an easy and practical way to use icons in your Dear ImGui application.
A common pattern is to merge the icon font within your main font, so you can embed icons directly from your strings without
having to change fonts back and forth.
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 Setup:
// Merge icons into default tool font
#include "IconsFontAwesome.h"
ImGuiIO& io = ImGui::GetIO();
io.Fonts->AddFontDefault();
ImFontConfig config;
config.MergeMode = true;
config.GlyphMinAdvanceX = 13.0f; // Use if you want to make the icon monospaced
static const ImWchar icon_ranges[] = { ICON_MIN_FA, ICON_MAX_FA, 0 };
io.Fonts->AddFontFromFileTTF("fonts/fontawesome-webfont.ttf", 13.0f, &config, icon_ranges);
Example Usage:
// Usage, e.g.
ImGui::Text("%s among %d items", ICON_FA_SEARCH, count);
ImGui::Button(ICON_FA_SEARCH " Search");
// C string _literals_ can be concatenated at compilation time, e.g. "hello" " world"
// ICON_FA_SEARCH is defined as a string literal so this is the same as "A" "B" becoming "AB"
See Links below for other icons fonts and related tools.

Read about oversampling here:
https://github.com/nothings/stb/blob/master/tests/oversample
If you have very large number of glyphs or multiple fonts, the texture may become too big for your graphics API.
The typical result of failing to upload a texture is if every glyphs appears as white rectangles.
In particular, using a large range such as GetGlyphRangesChineseSimplifiedCommon() is not recommended unless you
set OversampleH/OversampleV to 1 and use a small font size.
Mind the fact that some graphics drivers have texture size limitation.
If you are building a PC application, mind the fact that your users may use hardware with lower limitations than yours.
Some solutions:
- 1) Reduce glyphs ranges by calculating them from source localization data.
You can use ImFontGlyphRangesBuilder for this purpose, this will be the biggest win!
- 2) You may reduce oversampling, e.g. config.OversampleH = config.OversampleV = 1, this will largely reduce your texture size.
- 3) Set io.Fonts.TexDesiredWidth to specify a texture width to minimize texture height (see comment in ImFontAtlas::Build function).
- 4) Set io.Fonts.Flags |= ImFontAtlasFlags_NoPowerOfTwoHeight; to disable rounding the texture height to the next power of two.
