Fonts are rasterized in a single texture at the time of calling either of io.Fonts.GetTexDataAsAlpha8()/GetTexDataAsRGBA32()/Build().
If you want to use icons in ImGui, a good idea is to merge an icon font within your main font, and refer to icons directly in your strings.
You can use headers files with definitions for popular icon fonts codepoints, by Juliette Foucaut, at https://github.com/juliettef/IconFontCppHeaders

USING ICONS
---------------------------------
Using an icon font (such as FontAwesome: http://fontawesome.io) is an easy and practical way to use icons in your ImGui application.
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.
To refer to the icon from your C++ code, you can use headers files created by Juliette Foucaut, at https://github.com/juliettef/IconFontCppHeaders
// Merge icons into default tool font
#include "IconsFontAwesome.h"
ImGuiIO& io = ImGui::GetIO();
io.Fonts->AddFontDefault();
ImFontConfig config;
config.MergeMode = true;
const ImWchar icon_ranges[] = { ICON_MIN_FA, ICON_MAX_FA, 0 };
io.Fonts->AddFontFromFileTTF("fonts/fontawesome-webfont.ttf", 13.0f, &config, icon_ranges);
// Usage, e.g.
ImGui::Text("%s Search", ICON_FA_SEARCH);
