TYPO3 Core

We have a template in which we have a <f:format.date format="%B">@{eventDate.dateTimeStamp}</f:format.date> this outputs the month
localised. It works well, but the problem is that some months are not showing because they have entities not encoded. For example if month is March but localised in Catalan (Març), this month is not showing.

Our solution at this moment is change line 114 of the viewhelper:

return strftime($format, $date->format('U'));

for:

return htmlentities(strftime($format, $date->format('U')));
