ID: 29955 User updated by: jan at horde dot org -Summary: mb_strtoupper() / lower() broken with some locale Reported By: jan at horde dot org -Status: Closed +Status: Open Bug Type: mbstring related Operating System: Linux PHP Version: 5CVS, 4CVS (2004-09-02) Assigned To: hirokawa New Comment:
Any chance this is going to be backported to PHP 5.2? I guess mbstring is going to be obsolete with the Unicode and ICU support in PHP 6. Previous Comments: ------------------------------------------------------------------------ [2005-12-23 14:56:27] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php6.0-latest.tar.gz For Windows: http://snaps.php.net/win32/php6.0-win32-latest.zip Turkish language support is added in CVS HEAD. When mbstring.language = Turkish, Turkish case filding will be performed in ISO-8859-9. (upper:0x69 -> 0xdd, lower:0x49->0xfd) Otherwise, normal case folding is performed. (upper:0x69 -> 0x49, lower:0x49->0x69) ------------------------------------------------------------------------ [2005-12-23 14:28:29] [EMAIL PROTECTED] "man iso-8859-9" will tell you. "i" maps to "0xdd" and "0xfd" maps to "I" See also: http://www.eki.ee/letter/chardata.cgi?lang=tr+Turkish&script=latin ------------------------------------------------------------------------ [2005-12-23 14:24:06] jan at horde dot org See http://www.gymel.com/charsets/ISO8859-9.html#U0069 and http://www.gymel.com/charsets/ISO8859-9.html#U0049 under "Bemerkungen:" (remarks). ------------------------------------------------------------------------ [2005-12-23 14:10:05] [EMAIL PROTECTED] I don't know which is the standard way (0x49 or 0xdd). In ISO-8859-9 (Turkish), upper case of 'i' (0x69) always should be translated to 'I' with dot (0xdd) ? If yes, please let me know some URLs which describe the mapping. ------------------------------------------------------------------------ [2005-05-13 08:00:26] [EMAIL PROTECTED] Turkish locale would need complete overhaul on the entire extension because the locale's character properties and required case folding behaviour are very special. PHP-ICU extension could support anything, but that's just an ongoing work by l0t3k. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
