My Issue/Question:

//set font size to 88 or great size

Minimal, Complete and Verifiable Example code:

With the current system it is unlikely you can use GetGlyphRangesChineseFull() with such a big size. See link above for workarounds.

When I use freetype2.xx, 360 or greater font size also ok!. But I don't know how replace it with freetype in imgui.

Ok. I did it now. Use freetype. Thanks a lot!

I think font control: When I draw string, alloc texture with string。Now when I add ttf， and Imgui create all texture。But I real use
a little。
