I’m working on an Arabic font, I want to include an existing Latin font to merge with it, my question is what is the technically-correct way to do this and have the Latin (fully) functioning along with my Arabic one, (knowing that I own the license for the Latin one), the end result would be 1 bilingual font.
You can use MergeGlyphs. And if x-heights differ too much, you can use the shoulderHeight parameter in Font Info > Masters to have an Arabic metric line instead of the x-height.
If I open the Latin font file “otf” inside glyphs > update glyphs info, then copy all the Latin glyphs needed, then switch to my Arabic font and paste glyphs, what am I doing wrong or missing here?
Sounds fine. Have you been experiencing any problems?
