ImFontGlyphRangesBuilder

[project224]

i am trying to add support for these chars "šđč枊ĐČĆŽ"
code is called before imgui_app;

GetGlyphRangesDefault returns these ranges
0x0020, 0x00FF,
0x0100, 0x017F, // Latin Extended-A

ImVector<ImWchar> ranges;
ImFontGlyphRangesBuilder builder;
builder.AddRanges(io.Fonts->GetGlyphRangesDefault()); 
builder.BuildRanges(&ranges);                        

io.Fonts->AddFontFromFileTTF("C:\\Windows\\Fonts\\Tahoma.ttf", 18, NULL, ranges.Data);
io.Fonts->Build();'

rendered text

See
https://github.com/ocornut/imgui/blob/master/docs/FAQ.md#q-i-integrated-dear-imgui-in-my-engine-and-little-squares-are-showing-instead-of-text

And use tools such as the ones mentioned here:
https://github.com/ocornut/imgui/blob/master/docs/FONTS.md

Perhaps you are loading a font but texture hasn't been updated in the Backends.
Please be more specific with what works and what doesn't to get help. Thank you.

is calling font code before imgui_app fn correct?;

[ocornut]

I don’t know what imgui_app is.

sorry; https://github.com/pplux/imgui-app it might be the issue with this project

[ocornut]

Yes please look at imgui_app source code or ask them about it.
