Description Christian von Schultz 2009-04-08 13:10:39 UTC

Several unicode characters are rendered incorrectly in several applications when the Mathematica5*.ttf fonts are present. Affected applications include Mozilla Firefox and gnome-extra/gucharmap-2.24.3. I'm going to attach screenshots with gucharmap, with and without these fonts to make my point clear.

Affected characters include nabla (U2207), subset (U2282), superset (U2283) and not-a-subset-of (U2284). The screenshots have subset (U2282) highlighted. It is supposed to look something like the letter "C", but instead we get the "maps-to" arrow.

Reproducible: Always

Steps to Reproduce:
1. Start gucharmap (2.24.3)
2. Goto unicode block "Mathematical operators", choose subset (U2282).
3. If the font is "Sans" and Mathematica5*.ttf is installed, things break. With the font setting "Serif" or without Mathematica5*.ttf everything works.

Actual Results:  
See screenshots "2009-04-08_with_5_and_5m.png" (broken behaviour); "2009-04-08_with_5_not_5m.png" (broken behaviour, sligtly different - this is after mv /usr/share/fonts/mathematica-fonts/Mathematica5.ttf .)

Expected Results:  
See screenshot "2009-04-08_not_5_not_5m.png" - this is after both 
mv /usr/share/fonts/mathematica-fonts/Mathematica5.ttf .
and
mv /usr/share/fonts/mathematica-fonts/Mathematica5m.ttf .

On unrelated note, which font does provide correct 
glyphs for you ?

For font setting "Sans" it is "Mathematica1".
For font setting "Serif" it is "Times".
