Change to 100% case-insensitive function names has bigger probability of BC break. I think I've seen code which used functions in a way that depended on case insensitive lookups and same code had problems with Turkish, because case insensitive dependency was only on latin I. Option 1 maintains BC for ascii names. high bit characters don't break only in some locales. You will be lucky until you hit something in 0xC0-0xDF range that does not have direct match in 0xE0-0xFF range, you will enter minefield, if you use 0x80-0xBF and code will be hosed when locale does not support any usual iso-8859-1 high-bit characters matching. -- Tomas -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
