Description of the Issue

When code highlighting for TeX is applied, "&" is displayed as "\ " (backslash space), i.e. the "&" is not displayed.

The same issue also arises with some other languages, including Assmembly, C++, Fortran, Java, Matlab, Pascal and Perl. However, other languages including Batch, Makefile, Postscript and Shell do not cause this behavior.

Steps to Reproduce the Issue

1. Open Notepad++
2. Type "&"
3. Choose Language -> T -> TeX

Expected Behavior

The "&" should be displayed blue and bold, as all macros are.

Actual Behavior

Only the "" is displayed blue and bold, the "&" is not displayed at all.
