[nc] Technical: KDE/Konsole/KMail do not recognise Ubuntu Mono as being monospace (zero-width glyphs)

[Marcin Juszkiewicz]

I installed Ubuntu Beta Mono R17 font and "fc-list" shows it, I can not select it in Konsole (my main terminal app) or KMail (as monospace for message view).

Font can be selected in gVim, gnome-terminal as a font but both those apps does not limit list of fonts to monospace ones.

codeman38: has done some work on this (I thought we'd already nailed it by getting rid of the overwide advances on the polytonics and the ffi/ffl ligatures. There's two avenues:

  1. the OS/2 metadata
  2. zero-width codepoints that should be mono-width

[Cody Boisclair (codeman38)]

I've just confirmed that the issue is indeed the zero-width glyphs. Using my patched version of the font, it does show up in KDE's selection dialog for monospaced fonts.

(Forgot to mention, for the record, that the patch mentioned in the previous comment is available in Comment 8 of Bug 788757 as a Python script to modify the font.)

[Rich Johnson (nixternal)]

Installed the fonts, ran the script, regenerated the cache, and I still can't get this to show up in KDE apps.

[Rich Johnson (nixternal)]

Never mind that last entry, I didn't notice it created /fixed in the directory. Move the fonts out and regenerated the cache and all works now. Sorry about that.

[Marcin Juszkiewicz (hrw)]

Works fine for me in saucy.
