Subject: [PATCH] Update rust syntax: char literal (#2162)

Highlight character literals started with a single quote (').
Importantly this ensures correct highlighting for the character literal '"'.
Limitation: rust char literals contain exactly one character, however this isn't checked by the highlighter.

Closes #2160
