I have changed the fonts again recently, see Isabelle/ecb74607063f. I've
made a brief test on my MacMini with High Sierra, and it appears to work.


Normally "isabelle components -a" should give you the resulting ttf
files, and Isabelle/jEdit should pick them up.

This can be prevented by having IsabelleText.ttf / IsabelleTextBold.ttf
installed on the system by accident (on macOS in some Library/Fonts
directory, FontBook should be able to tell you). You should remove such
spurious copies of the Isabelle fonts.
