Syntax highlighting is controlled by a lexer written in C++ that
identifies syntactic elements.   You have selected to use the C
language lexer where single quotes identify character literals.

You should try other languages, but most use single quote as a
character sequence opening.  Perhaps Lisp would be more useful since
single quote has a similar meaning in Lisp to Maxima (and come to
think of it I believe Maxima is written in Lisp)..

You could create a colour scheme that sets the styling for characters
to something neutral, but nothing in the rest of the line (or at least
to the next single quote, that being what C requires to close a
character) will be syntactically analysed since the lexer thinks its a
character literal.

For anything else you would have to change the lexer to stop it
identifying characters when it encounters a single quote.  The lexer
is part of the Scintilla editing widget Geany uses and is in the
scintilla directory.
