Finally found a use for the hideous Unicode "fi" ligature: fitting quotes in 140 chars.https://twitter.com/RichFelker/status/882976573510602752 …
Yes. The most hideous part is that several PDF readers/converters produce them in output or clipboard copies for Adobe "fi" glyph...

-
Hmm, should there be a monospace font that makes a n-char ligature n characters wide?
-
For character-cell fonts it's not possible without getting implementors to agree on changing wcwidth([those chars])...
-
Not sure what assumptions applications are entitled to make about "monospace" fonts but it may be a problem there too. :-(

The Slack iOS app produces it if I type “fi”.pic.twitter.com/ppZunKcGox

No, the font just has a presentation form.

Blame AdobeStandardEncoding & their PDF authoring s/w - they're stored as the ligature & most s/w maps to U+FB01 instead of decomposing it.
-
Understood. Failure to decompose it is the bug/misbehavior. Because it was just a presentation form in the PDF, not semantically U+FB01.
-
Yeah, the usual implementation of doing CharCodeToUnicode conversions is 256-entry table that maps to Unicode codepoint 1:1 b/c laziness.
