From: Operating system: OSX (though probably all) PHP version: 5.3.8 Package: Unicode Engine related Bug Type: Bug Bug description:UTF-8 functions doesn't respect unicode equivalence
Description: ------------ Quote from http://en.wikipedia.org/wiki/Unicode_equivalence: "...the code point U+006E (the Latin lowercase 'n') followed by U+0303 (the combining tilde 'âÌ') is defined by Unicode to be canonically equivalent to the single code point U+00F1 (the lowercase letter 'ñ' of the Spanish alphabet). Therefore, those sequences should be displayed in the same manner, should be treated in the same way by applications such as alphabetizing names or searching, and may be substituted for each other." It might be this is more a case of just documenting that the unicode functions don't support unicode equivalence (for completeness). Test script: --------------- echo "Output recorded from a terminal interpreting UTF-8\n\n"; var_dump("\x6e\xcc\x83"); var_dump(utf8_encode("\xf1")); var_dump(utf8_decode("\x6e\xcc\x83") == "\xf1"); var_dump(mb_convert_encoding("\x6e\xcc\x83", "ISO-8859-1", "UTF-8") == "\xf1"); Expected result: ---------------- Output recorded from a terminal interpreting UTF-8 string(3) "ñ" string(2) "ñ" bool(true) bool(true) Actual result: -------------- Output recorded from a terminal interpreting UTF-8 string(3) "ñ" string(2) "ñ" bool(false) bool(false) -- Edit bug report at https://bugs.php.net/bug.php?id=60412&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=60412&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=60412&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=60412&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=60412&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=60412&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=60412&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=60412&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=60412&r=needscript Try newer version: https://bugs.php.net/fix.php?id=60412&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=60412&r=support Expected behavior: https://bugs.php.net/fix.php?id=60412&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=60412&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=60412&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=60412&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=60412&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=60412&r=dst IIS Stability: https://bugs.php.net/fix.php?id=60412&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=60412&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=60412&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=60412&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=60412&r=mysqlcfg
