Well, if the UTF-8 data is valid (which I suppose would be validated the same was as any UTF-8-supported function validates it) then all bytes that make up the UTF-8-character will be in range of 0x80 and 0xF7. That's the nice thing about UTF-8 - no character with code points above 128 will produce bytes where the uppermost bit is zero (0x00 to 0x7F) -- - Peter Brodersen -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
