Bug #69114 [NEW]: Undocumented 5.6 BC Break: default encoding ISO-8859-1 -> UTF-8

From: maggus dot staab at googlemail dot com Operating system: PHP version: 5.6.6 Package: Documentation problem Bug Type: Bug Bug description:Undocumented 5.6 BC Break: default encoding ISO-8859-1 -> UTF-8 Description: ------------ With PHP5.6 the default encoding changed from ISO-8859-1 to UTF8. This bc break is not mentioned in the list of BC changes: http://php.net/manual/en/migration56.incompatible.php The charset related docs mention that iconv.input_encoding iconv.output_encoding iconv.internal_encoding mbstring.http_input mbstring.http_output mbstring.internal_encoding is deprecated as of 5.6 and we should use default_charset instead: http://php.net/manual/en/ini.core.php#ini.default-charset For non-utf8 legacy app which are updated to PHP5.6 it is not clearly documented how the path is. just setting ini_set('default_charset', 'ISO-8859-1'); does not do the trick, because of the deprecated above mentioned settings still default to UTF8. It feels like non-utf8 apps can only be configured using deprecated settings like (which does not work by the way) ini_set('default_charset', 'ISO-8859-1'); iconv_set_encoding("internal_encoding", 'ISO-8859-1'); iconv_set_encoding("output_encoding", 'ISO-8859-1'); iconv_set_encoding("input_encoding", 'ISO-8859-1'); How is the correct way to migrate a non-utf8 app to 5.6? How should the settings look like to be compatible to 5.5 defaults and also be future proof (so dont rely on deprecated settings)? Such a path should be documented in the migration guide. -- Edit bug report at https://bugs.php.net/bug.php?id=69114&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69114&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69114&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69114&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69114&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69114&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69114&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69114&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69114&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69114&r=support Expected behavior: https://bugs.php.net/fix.php?id=69114&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69114&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69114&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69114&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69114&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69114&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69114&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69114&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69114&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69114&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69114&r=mysqlcfg
