Watch your mouth! :-PIIRC, the original message was concerned only by the percent sign (or so I understood), so I addressed only this case.
I think that the control characters are those below Ascii 32, not the chars listed above.I suggest that (not tested) : pattern = string.gsub(generatedPattern, "(%c)", "%1") newString = string.gsub(oldString, pattern, replace) %c represents all control characters
Well, I don't disagree with you, it should be easy to add an additional, optional argument, without breaking compatibility.If it does not work, [^%w] must work because all escaped non-alphanumeric character represent the character itself Is it possible to add a parameter to switch to a plain text replacement ...? It would be very useful ... Why should I use regular expressions when I only need plain text replacement ?
