Note: This issue might also apply to deck titles, and could as well be a general… problem of nextcloud. I have not checked it yet, but I guess it will show, if the problem lies deeper in some common API
### Steps to reproduce
Create a card with a title "αβγδεζηθικλμνξοπρστυφχψωαβγδεζηθι" (That is 34 greek characters)
try to link this card to anything, a deck, a card, a file, or a conversation. It will fail.
For reference, if you remove the last character, making the length 33, linking to the other objects works as expected.
Note:
It looks like there might be an encoding issue here, as for example url encoded characters like these, would eat up 99 characters in the case of a 33 character string of non-latin characters and 102 in the case of 34 non-latin characters. This might be a combination of problems - the first being the characters being counted wrong due to encoding issues, and the second being an imposed limit of 100 characters, which, i think, was the hard limit for titles in the past.
### Expected behaviour
Link should complete
### Actual behaviour
Link fails responding with "Failed to create a project" in the UI. See browser log below for related network info.
