main font. Then you can refer to icons within your strings.
You may want to see ImFontConfig::GlyphMinAdvanceX to make your icon look monospace to facilitate alignment.
(Read the 'misc/fonts/README.txt' file for more details about icons font loading.)
With some extra effort, you may use colorful icon by registering custom rectangle space inside the font atlas,
and copying your own graphics data into it. See misc/fonts/README.txt about using the AddCustomRectFontGlyph API.
Q: How can I load multiple fonts?
A: Use the font atlas to pack them into a single texture:
