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 .
Created attachment 187683 [details] Screenshot of broken behavoiru
Created attachment 187685 [details] Still broken, without Mathematica5.ttf
Created attachment 187686 [details] This is how it should look, here without Mathematica5*.ttf
On unrelated note, which font does provide correct glyphs for you ?
