How will the REGEX_REPLACE() function work? The second answer - I thought that the simple way of getting multi-byte > support, would be to remove Henry Spencer library, and put some modern > regex implementation instead.

Did you already have a library picked out? Are there any requirements to license and language?

However, I do not have an unlimited amount of time for this project. I'll look into Henry Spencers old library and let you know what I decide to do. -- Line Bie Pedersen
