The instruction of converting otf to ttf on Mac

Reason

Microsoft has trouble with .otf files, opting to emit a bitmap rather than text when generating PDFs that reference these fonts. We should convert all our existing .otf files to .ttf and redploy them.

Steps

• Install fontforge
  brew install fontforge
• Use fontforge script to convert otf file
  1. create a fontforge script convert.ff file like following, first line is the path of your fontforge, default one is #!/usr/local/bin/fontforge
     

    #!/opt/homebrew/bin/fontforge
    i=1
    while ( i<$argc )
      Open($argv[i])
      Generate($argv[i]:r + ".ttf")
      i = i+1
    endloop
  

  2. chmod +x convert.ff
  3. convert all otf files to ttf.
     ./convert.ff *.otf
