[TYPO3-core] RFC #12661: Problem with german "Umlaute" in BE file list, no thumbs generated

[Jigal van Hemert]

Hi,

this is a SVN patch request.

Type: Bugfix

Bugtracker references:
http://bugs.typo3.org/view.php?id=12661

Branches: 4_3, 4_2, trunk

escapeshellarg() drops "special characters" (diacriticals, etc.) if 
there is no appropriate locale set for LC_CTYPE. This results in an 
incorrect path and/or filename and no thumbnail is generated in the 
backend or frontend.

Solution: if $TYPO3_CONF_VARS['SYS']['UTF8filesystem'] is set LC_CTYPE 
locale is set with a generally available locale which supports the utf-8 
character set. After escapeshellarg is called the original locale is 
restored.
