Afaik it can be even more (diacritics on rare characters) up to 16 bytes or so. Unicode is quite complicated ( http://www.stack.nl/~marcov/unicode.jpg +/- 1400 bigger than A4 pages ). I browsed through it, and ieew. FPC and Lazarus have a considerable backlog on unicode problems and enhancements. Partially this is probably historical, the bulk of the developers can live with the fairly standard Latin 1 (ISO 8859-1(5)) encoding, or even with plain ascii. To really let unicode usage improve significantly, I think there must be a team (or at least one long-term volunteer) that can really start to dig into these issues and use/need unicode every day. Starting bottom up, testing FPC unicode support (language), resolving/pinpoiting/reproducing bugs, providing unicode alternatives for the string routines, testing unicode cleanness of various system libraries etc etc. Nothing is easy with language and internationalization, and even Ascii is not easy. I had to change a simple capitalisation routine last week because a customer pointed out to me that in Dutch "ij" is one single letter in typography, and must be capitalized in its entirety. This seemed logical to me, as a native speaker, but while coding the capitalization routines I didn't think of it. _________________________________________________________________ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
