Can't read RSS Feed from Joomla 4 using different RSS-Classes

Hello,

I found out, that in joomla 3 if there is a linebreak in the CDATA there is always a CR/LF. In joomla 4 there is only a LF.

This is the only relevant difference I could find between the xml-Code of the different feeds.

The Syndicate-Classes I use seem not be able to deal with that.

What can I do? Any suggestionsß

best regards.
