I was under the impression they have been very carefully designed to do the right thing with characters represented by multiple codepoints, which is something the String version *cannot* do. It would help if Bryan were involved with this discussion, though. (I'm cc:ing him on this.) Since the whole point of Data.Text is to handle stuff like this properly I would be surprised if your assertion that > upcase :: String -> String > > upcase = map toUpper > > This is no more incorrect than > upcase = Data.Text.map toUpper > is correct. -- brandon s allbery allber...@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms
