Bug #54688 [NEW]: case insensitive search of stripos does not work when searching äöü in utf-8

From: Operating system: Linux PHP version: 5.3.6 Package: Strings related Bug Type: Bug Bug description:case insensitive search of stripos does not work when searching äöü in utf-8 Description: ------------ --- From manual page: http://www.php.net/function.stripos#Description --- If some text is encoded in UTF-8 and I search this text with stripos for a string with (e.g.) lower case Umlaut (e.g. ü), this function does not find the upper-case Umlaut (Ü). That means case-insensitive does not work for Umlauts if a text file is encoded UTF-8. Test script: --------------- File test.txt contains "Übermut" and is encoded UTF-8 without BOM <?php $text = file_get_contents("test.txt"); echo $text."<br>"; $str = "über"; if (($pos=stripos($text,$str)) !== false) echo $str." gefunden"; else echo $str." nicht gefunden"; ?> Expected result: ---------------- Übermut über gefunden Actual result: -------------- Übermut über nicht gefunden -- Edit bug report at http://bugs.php.net/bug.php?id=54688&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=54688&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=54688&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=54688&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=54688&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=54688&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=54688&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=54688&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=54688&r=needscript Try newer version: http://bugs.php.net/fix.php?id=54688&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=54688&r=support Expected behavior: http://bugs.php.net/fix.php?id=54688&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=54688&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=54688&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=54688&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=54688&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=54688&r=dst IIS Stability: http://bugs.php.net/fix.php?id=54688&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=54688&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=54688&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=54688&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=54688&r=mysqlcfg
