The values \u0000 and \uFFFF should never occur in XML and can be used as sentinels if your algorithm works on UTF-16 code units. For the purpose of indexing text, working on UTF-16 code units as opposed to working on Unicode characters may well be good enough. In that case, a surrogate pair can be treated as two adjacent "characters". (Note that even when operating on UTF-32, you can have tightly-coupled characters when there is a base character followed by combining marks, so working on Unicode characters does not buy you inter-character independence.) -- Henri Sivonen hsivonen@i... http://hsivonen.iki.fi/
