But that tells us nothing about the quality of Erlang's Unicode support. Is it easy in Erlang to encode a string to its UTF-8 or Latin-1 representation and vice-versa? Are there utilities in Erlang to check whether a character is a punctuation symbol, a letter or a digit? Are there utilities to normalize Unicode strings? This one is important if you need to compare two strings.

Sorry if I sound a bit pedantic, but there is a lot more to good Unicode support than using wide characters.
