Doc #52024 [NEW]: strtr behaves strangely with multi bytes strings

From: Operating system: Linux Debian testing amd64 PHP version: 5.3.2 Package: Strings related Bug Type: Documentation Problem Bug description:strtr behaves strangely with multi bytes strings Description: ------------ strtr() only translates _bytes_, not characters. When translating a multi-byte character to a single byte character, only the first byte is converted, resulting in a broken string. The examples given in the doc work with an ISO-8859-1 encoding of the source file, but not with UTF-8. IMHO, two solutions; 1) Fix the function. But then the function would need to guess the file encoding. Hmmm....PHP6? 2) Fix the doc. The doc title, "strtr — Translate certain characters", is misleading. Either replace "characters" by "bytes", or add somewhere on the page that it only works on single-byte encodings. A big warning would be useful. Test script: --------------- // in an UTF-8 file echo strtr("’", "’", "'"); echo strtr("äåö", "äåö", "aao"); // example from php.net Expected result: ---------------- 'aao Actual result: -------------- '��oao�o� -- Edit bug report at http://bugs.php.net/bug.php?id=52024&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52024&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52024&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52024&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52024&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52024&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52024&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52024&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52024&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52024&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52024&r=support Expected behavior: http://bugs.php.net/fix.php?id=52024&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52024&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52024&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52024&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52024&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52024&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52024&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52024&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52024&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52024&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52024&r=mysqlcfg
