[TYPO3-core] RFC: Bug #4183: Incorrect display in htmlArea RTE of utf-8 labels defined in PageTSConfig

[Stanislas Rolland]

Hi,

This is an SVN patch request.

Type: Bugfix

Problem:
When the backend is forced to utf-8, labels or names (for classes, 
colors or fonts) directly entered in PageTSConfig are entered as utf-8.

PageTSConfig may be set through some php script. Perhaps, if 
PageTSConfig is set from a php script, the values should be specified 
through some language file (LLL:EXT:file or LLL:file).

If the values are entered directly in PageTSConfig and processed through 
$LANG->sL, $LANG->sL will apply a charset conversion if 
$LANG->origCharset is not utf-8. For many languages, $LANG->origCharset 
is NOT utf-8.

Solution:
Do not use $LANG->sL when the label is defined by a simple string rather 
than by reference to a locallang file.

Comments:
I tested the attached patch in a utf-8 backend (I think whatever the 
backend charset, the problem could arise if it is not the same as the 
'original' charset). Would appreciate feedback on the approach.

The patch fixes another problem apparently not reported in the 
bugtracker: the colors and classes labels were localized using the 
language of the content element rather than the language of the backend.
