A little bit more info is probably good here. For example, a problem with standard lowercase comparison is that it fails with many non-english languages. Stringprep is more or less a way to provide standardization of strings similar to lowercasing. References: RFC 3454, http://www.faqs.org/rfcs/rfc3454.html "This document describes a framework for preparing Unicode text strings in order to increase the likelihood that string input and string comparison work in ways that make sense for typical users throughout the world. The stringprep protocol is useful for protocol identifier values, company and personal names, internationalized domain names, and other text strings." Usage of stringprep is mandatory for XMPP, see http://www.jabber.org/ietf/draft-ietf-xmpp-core-23.txt (search for "stringprep"). Concerning jabberd14: jabberd 1.4.3 does not use stringprep (it uses lowercasing and therefore for example treats [EMAIL PROTECTED] as a different user than [EMAIL PROTECTED]). jabberd14-CVS however supports stringprep by using the libidn library (thanks to Matthias Wimmer, "configure --enable-idn").
