(B) Use fonts from external files
You need to set io.FontTexUvForWhite to UV coordinates pointing to a white pixel in the texture.
You need to set io.Font->TexUvForWhite to UV coordinates pointing to a white pixel in the texture.
You can either locate a white pixel manually or use code at runtime to find or write one.
The OpenGL example include sample code to find a white pixel given an uncompressed 32-bits texture:
// Automatically find white pixel from the texture we just loaded
// (io.FontTexUvForWhite needs to contains UV coordinates pointing to a white pixel in order to render solid objects)
// (io.Font->TexUvForWhite needs to contains UV coordinates pointing to a white pixel in order to render solid objects)

{
io.FontTexUvForWhite = ImVec2((float)(tex_data_off % tex_x)/(tex_x), (float)(tex_data_off / tex_x)/(tex_y));
