I suggest that (not tested) : pattern = string.gsub(generatedPattern, "(%c)", "%1") newString = string.gsub(oldString, pattern, replace) %c represents all control characters 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 ? -- <http://louve.dyndns.org> ou <http://mildred632.free.fr> Le courrier E-mail est une correspondance privée.
