FontData is incorrect, or FontNo cannot be found

My Issue/Question: I'm getting FontData is incorrect, or FontNo cannot be found., and I tried searching that region, but I genuinely have no idea what FontData is and how it should be set.

// Here's some code anyone can copy and paste to reproduce your issue

{
        // I'm trying a custom menu I found
        ImFontConfig fontConfig;

	fontConfig.OversampleH = 1;
	fontConfig.OversampleV = 1;
	fontConfig.PixelSnapH = 1;

	name = io.Fonts->AddFontFromFileTTF("C:/Users/bruzi/Desktop/app/src/gui/fonts/MuseoSansCyrl_1.otf", 
		22.0f, NULL, io.Fonts->GetGlyphRangesJapanese());
}

Of course you'd need to change the path if you want to reproduce, those are initialized once. I have no idea how to fix this, thanks.

Debugging gives me that FontNo is 0, is it normal?

Fixed it, I was reading fonts as an int instead of unsigned char (x86)
