Description
If working with Image-Files for Retina-Displays there is the need for filenames with the character @ in it, e.g. image@2x.jpg.
The character @ is prevented by the function cleanFileName in class.t3lib_basicfilefunc.php (respectively BasicFileUtility.php for version >6.0).
But the behavior is inconsistent. If $GLOBALS['TYPO3_CONF_VARS']['SYS']['UTF8filesystem'] is set, the character @ is allowed, because \x40 is not excluded by the regex.
Therefor, I suggest to allow the @ character in filenames in non-utf8-filesystems as well.
To achieve this, the line
$cleanFileName = preg_replace('/[^.[:alnum:]_-]/', '_', trim($fileName));
should be changed to
$cleanFileName = preg_replace('/[^.[:alnum:]@_-]/', '_', trim($fileName));
