Perhaps we could run such substitutions at a time where strings have been 
removed from the code during preparse. The preparser works by stripping 
strings and comments, then transforming the code, then putting them back 
in. So while strings and comments can contain arbitrarily ugly stuff, the 
rest should be reasonably sane, and any of the dashes U+2010 through U+2015 
could be turned into minus, while ×, ∙ and U+2062 (invisible times, often 
used in MathML) could become times. Unless you want × as cross_product, or 
something like that…
