If you use accents or modified letters(examnples:"a" with acute,lowercase "i" without dot,"g" with breve and more)they can be used but that letters that have accent doesn't appear when you make a save with that,as it happens with ""n" with tilde/hair"
Theres no logic of having they anyway since the comunity use english in the saves
yes,that ones only can be used in TPTMP without problems
a bit too late but not only in TPTMP but also in TPT save descriptions
put proof of it,idk if it is possible in TPT descriptions
For example
thanks for the explanation of comnpatible characters in descriptions LBPHacker!
