#49412 [NEW]: htmlspecialchars(): Add note that most charsets don't make any difference

From: thomas at landauer dot at Operating system: All PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: htmlspecialchars(): Add note that most charsets don't make any difference Description: ------------ From the 12 charsets listed in the htmlspecialchars() documentation, the following 7 are equivalent: *) ISO-8859-1 *) ISO-8859-15 *) UTF-8 *) cp866 *) cp1251 *) cp1252 *) KOI8-R Reason: The five characters affected by htmlspecialchars() [& < > " '] are all on the same position in these charsets. So for most people, the charset parameter is totally irrelevant. My suggestion: Include a note about this fact under the charset table. -- Edit bug report at http://bugs.php.net/?id=49412&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=49412&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=49412&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=49412&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=49412&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=49412&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=49412&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=49412&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=49412&r=needscript Try newer version: http://bugs.php.net/fix.php?id=49412&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=49412&r=support Expected behavior: http://bugs.php.net/fix.php?id=49412&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=49412&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=49412&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=49412&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=49412&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=49412&r=dst IIS Stability: http://bugs.php.net/fix.php?id=49412&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=49412&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=49412&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=49412&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=49412&r=mysqlcfg
