255 Max Characters

There seems to be a character limit in the Tags/Genres (In the OPDS feed they are shown under content in the attribute label) you can give via ComicInfo.xml. 
When there are more than 255 characters, everything after it is cut off, leading to splitted and entirely missing tags. 

As there is technically no limit in how many characters XML attributes (and therefore OPDS feeds) can handle, I am relatively sure that this is due to the way the value is stored in the database, so I'd be glad if this value would get a bit more space.
