Addresses bug #49412. ------------------------------------------------------------------------ [2009-08-30 19:31:51] jani@php.net There is no such OS called "All". ------------------------------------------------------------------------ [2009-08-29 22:16:20] thomas at landauer dot at 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 this bug report at http://bugs.php.net/?id=49412&edit=1
