#51060 [NEW]: mb_check_encoding fails on correctly encoded iso-2022-jp string

From: areid at lumerical dot com Operating system: Linux (RHEL5) PHP version: 5.2.12 PHP Bug Type: mbstring related Bug description: mb_check_encoding fails on correctly encoded iso-2022-jp string Description: ------------ I have found that mb_check_encoding returns false when I pass it a string that I think is correctly encoded. It occurs when the string contains Roman characters encoded in the JIS X 0201-1976 character set. I cehcked that according to RFC 1468 this encoding is valid. Furthermore, mb_convert_encoding is able to decode this string. Reproduce code: --------------- $encoded = "\x1b(JTEST"; if(!mb_check_encoding($encoded,'ISO-2022-JP')) echo "check encoding failed\n"; echo mb_convert_encoding($encoded,'UTF-8','ISO-2022-JP')."\n"; Expected result: ---------------- I expect only the word "TEST" to be printed Actual result: -------------- "check encoding failed" is printed indicating that mb_check_encoding returned FALSE. "TEST" is also printed, showing that mb_chonvert_encoding successfully decoded the string. -- Edit bug report at http://bugs.php.net/?id=51060&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=51060&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=51060&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=51060&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=51060&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=51060&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=51060&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=51060&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=51060&r=needscript Try newer version: http://bugs.php.net/fix.php?id=51060&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=51060&r=support Expected behavior: http://bugs.php.net/fix.php?id=51060&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=51060&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=51060&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=51060&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=51060&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=51060&r=dst IIS Stability: http://bugs.php.net/fix.php?id=51060&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=51060&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=51060&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=51060&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=51060&r=mysqlcfg
