Thanks John, I'm replacing the use of Qt's QRegExp with boost regex. 
QRegExp::escape was used to ensure that when the user selects from a 
list of single char delimiters, which has many of the regex control 
characters, can be used to split a string. So in this case a simple 
mapping function suffices.

Thanks for the \Q ... \E info as well.
