Missing ligatures info for ENCLOSING KEYCAP characters

[monejava]

• Font version: 1.3
• Screenshots: Not necessary.
• Operating system: MacOSX
• Steps to Reproduce:

I'm currently trying to use the font from a PDF rendering library called ApacheFOP. The library does not support the non-BPM codepoints so I'm implementing the support (https://issues.apache.org/jira/browse/FOP-1969). That said I was able to print almost all the glyphs including flags (🇮🇹) and families (👨‍👩‍👦 ) using the ligatures table.

It looks like the font is missing the ligature info for the ENCLOSING KEYCAP characters (1⃣ 2⃣ etc..). I was wondering if it is a bug or an expected behavior.

Thanks

Sadly, it is currently expected behavior. 😦

Those are disabled, because there's no way to make this the default font and have them work as expected. This question is a OSX-specific duplicate of the Linux-specific #46. Keycaps require ligatures, ligatures require both original characters in the font. The only viable AFAIK workaround is described in #40 here: #40 (comment) But, that will either not work in OSX or replace your regular numbers.

I'm actually not sure how this is handled in Apple Color Emoji right now. I'll check that next week. Any other solutions or ideas are welcome!

Thanks for the very detailed response. I was expecting that there was a reason, but hoping that it was a bug 🤔.

Actually it doesn't matter that much the Operating System since I'm implementing the reading of the font via Software (in the ApacheFOP library) and the result get printed in a PDF.

I'll try to see if the #40 can help me. I'll get back to you.

Thanks.

I looked at Apple Color Emoji, the version from Yosemite (or earlier?), and they have the plain number glyphs within the font.
