CoreText seems to have an opinion about diffmerge fonts. Everything runs splendidly however.

Code: Select all

mh@thunderstorm ~/g/sqlminus/sqlminus --> git difftool

Viewing (1/1): 'sqlminus/sqlminus.py'
Launch 'diffmerge' [Y/n]:

I think that might have more to do with Mavericks than Core Text. Other users with Mavericks has reported this, but I haven't heard anything on any later OS.

Has anyone on a more recent OS tried this?
