#37775 [NEW]: [[cntrl]] class seems to kill some utf-8 strings...

From: stronk7 at moodle dot org Operating system: Windows XP PHP version: 5.1.4 PHP Bug Type: PCRE related Bug description: [[cntrl]] class seems to kill some utf-8 strings... Description: ------------ I was using one simple preg_replace() to clean strings from control characters and, under XP I found that some utf-8 characters are also modified although they don't contain control characters (\x-\1f and \7f) at all. Same code seems to work properly under MacOS X and linux. Please note that code below is utf-8 and should be pasted with the editor in that mode. The char failing seems to be the upper i with dieresis: Ï The example include the non-working example (first) plus two alternatives that work properly under XP. Ciao :-) Reproduce code: --------------- <?php $orig = "IIÏÏïï"; $dest = preg_replace("/[[:cntrl:]]/","",$orig); echo $dest; echo "\n<br>\n"; $orig = "IIÏÏïï"; $dest = ereg_replace("[[:cntrl:]]","",$orig); echo $dest; echo "\n<br>\n"; $orig = "IIÏÏïï"; $dest = preg_replace("/[\x-\x1f]/","",$orig); echo $dest; echo "\n<br>\n"; ?> Expected result: ---------------- Should return IIÏÏïï in the three alternatives. Actual result: -------------- This returns: II??ïï <--- incorrect <br> IIÏÏïï <--- correct <br> IIÏÏïï <--- correct <br> -- Edit bug report at http://bugs.php.net/?id=37775&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=37775&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=37775&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=37775&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=37775&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=37775&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=37775&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=37775&r=needscript Try newer version: http://bugs.php.net/fix.php?id=37775&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=37775&r=support Expected behavior: http://bugs.php.net/fix.php?id=37775&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=37775&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=37775&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=37775&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=37775&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=37775&r=dst IIS Stability: http://bugs.php.net/fix.php?id=37775&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=37775&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=37775&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=37775&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=37775&r=mysqlcfg
