Thanks for your comments.
Regarding the Hungarian language problem: I found an old version (2006) of the hyphenation dictionary, which doesn't include the special duplicated letters. It seems the newer dictionary - which you can download from your recommended location - is not compatible with this plug-in. But if you use the old dictionary the hyphenation is good. It will not break the words where it includes these problematic duplicated letters.
You can try this dictionary by downloading my attachment.

Thanks.
