Merge Font (Such as Thai and English)

Merge Font with fonttools

1. Install fonttools

brew install fonttools

2. Prepare the fonts

Put two fonts in a folder, e.g.

• MiSansLatin.ttf
• MiSansThai.ttf

3. Use pyftmerge

pyftmerge MiSansLatin.ttf MiSansThai.ttf

4. Rename the font (optional but recommended)

ttx merged.ttf

This creates a merged.ttx (XML). Open it, find the entries (IDs 1, 4, 6 are most important: font family, full name, PostScript name), and replace them with "MiSans".

Then rebuild:

ttx merged.ttx

You now get merged#1.ttf with the corrected name.
