Which one do you use for strings in HTML or XML in which UTF-8 has become the commonly accepted standard encoding? It's text, not binary, so I should choose Data.Text. But isn't there a performance penalty for translating from Data.Text's internal 16-bit encoding to UTF-8? http://tools.ietf.org/html/rfc3629 http://www.utf8.com/ Regards, Sean
