Fix #5760 also on Windows.

Browse Source 
The problem was due to the use of the wrong symbol for the slash.
The zero-width symbol for the \not operator was being used.
Using TeX fonts for all symbols gives now a better uniform look.
It is not possible using the alternative code even with Qt 5.4.1
because some glyphs are still missing.
