Testing this, I find that isAlpha is True also for 'º', but as the OP
claims, Haskell will use it as a(n infix) symbol.  Neither does
isSymbol (all False), isLetter (all True), isMark (False), nor
isPunctuation (Fals) help to separate these.

The HR defines 

    uniSymbol 	 -> 	 any Unicode symbol or punctuation 

but I couldn't find any clear way to identify of these.
