UTF8 displays as "??" on windows, untested on other OS.

Hello and thank you for your message!
Did you run the example without modification?
The example uses only the default font and character ranges of Dear ImGui.
If you want to display more characters, the application has to load a separate font file and enable the corresponding glyph ranges. This is what is meant by the text in the demo window "CJK text will only appear..." The referenced README.txt can be found in the Dear ImGui repository.
To get the characters shown (on Windows), you can modify the example in imgui-go_impl_glfw_gl3.go in the function createFontsTexture().
Instead of
image := io.Fonts().TextureDataAlpha8()
you put
fontAtlas := io.Fonts()
var builder imgui.GlyphRangesBuilder
builder.AddExisting(fontAtlas.GlyphRangesDefault())
builder.AddExisting(fontAtlas.GlyphRangesChineseFull())
ranges := builder.Build()
fontAtlas.AddFontFromFileTTFV("C:\\windows\\fonts\\msgothic.ttc", 16, imgui.DefaultFontConfig, ranges.GlyphRanges)
fontAtlas.SetTexDesiredWidth(8192)
image := fontAtlas.TextureDataAlpha8()
Then the demo looks like this:
Thank you very much. It is fixed. Also, may I ask where can I find document of Dear ImGui?
Great!
Dear ImGui is found here: https://github.com/ocornut/imgui . From there you can follow up on readme files, their Wiki, as well as the source (headers).
All the best!
