[erlang-questions] Of regexes and REs, and other irritating things...

I need to so some input sanitizing for use against MySQL.
"This isn't much of a \"test string\"; it'll have to do though."
Tried using the RE modules (yes, quad escaping crap) but the replacement
part for the back-references isn't working correctly. Instead of getting
"\;" it's actually interpreting the backslash all the way down. At least
it's not turtles all the way down.
So I went with a replacement of <92,"\\\\1"> thinking I'd get around it,
but it didn't work either. Closest I got was "\\;" in the string which is
still incorrect.
So regexp is deprecated in favor of RE, but yet RE's pretty shitty for this
kind of thing. I suppose I can just walk the list directly but then it's
incremental string-building.
Anyone have a "here dummy, you missed this NIF/built-in ... just use that"
to throw my way?
TIA!
