You're right - you can only code 65,536 characters with 3 UTF-bytes. U-00000000 - U-0000007F: 0xxxxxxx U-00000080 - U-000007FF: 110xxxxx 10xxxxxx U-00000800 - U-0000FFFF: 1110xxxx 10xxxxxx 10xxxxxx
Once you want to go higher than U-0000FFFF, you need up to 6 bytes: U-00010000 - U-001FFFFF: 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx U-00200000 - U-03FFFFFF: 111110xx 10xxxxxx 10xxxxxx 10xxxxxx 10xxxxxx U-04000000 - U-7FFFFFFF: 1111110x 10xxxxxx 10xxxxxx 10xxxxxx 10xxxxxx 10xxxxxx (http://www.cl.cam.ac.uk/~mgk25/unicode.html) Anyway... 65,536 is enough for me :) Sven > -----Original Message----- > From: Jochem van Dieten [mailto:[EMAIL PROTECTED] > Sent: Dienstag, 10.
