ImGui by default only loads glyphs for standard Latin characters (i.e. first 255). In order to load glyphs outside this range you need to pass in the requested range using a font config struct. The font config struct also allows setting other values such as font size, offset etc.
This PR allows specifying a font config struct with each font (now also supports passing multiple fonts)
example usage:
char const *fonts[] = {"C:\\Windows\\Fonts\\seguisym.ttf"};
ImFontConfig fontConfigs[1];
fontConfigs[0].MergeMode = true;
static const ImWchar glyphRanges[] = {
0x23E0,
0x23FF, // Media player icons
0x1F500,
0x1F505, // Restart icon
0,
};
fontConfigs[0].GlyphRanges = &glyphRanges[0];
fontConfigs[0].SizePixels = 30.0f;
fontConfigs[0].GlyphOffset.y += 5.0f; // Need to offset glyphs downward to properly center them
auto err = gfxImGuiInitialize(contextGFX, fonts, 1, fontConfigs);
