Sorting object in the tree and collate

Hi,
I noticed that the objects in the tree are not sorted correctly when they start with diacritical characters, for example Ł, Ś etc.
The problem is in the DataObjectController.php file where “…COLLATE utf8_general_ci ASC” is added to the SQL condition.
Is there a reason why it is hard code? Has anyone had a similar problem? Will changing COLLATE to utf8_unicode_ci significantly affect Pimcore performance?

Thanks for bringing it up! There is an issue in progress for the sorting in trees topic, might make sense to contribute your findings there
