Non-ASCII room aliases

[olmari]

Description

Element-web/desktop doesn't allow using non-ASCII characters when defining new local room alias, while matrix specifications perfectly allow for such thing.

Steps to reproduce

• Try adding new room alias that contains ~any non-ASCII character
• See Element telling "not possible"

Version information

• Platform: Both web (in-browser) and desktop, 1.7.23

Solution:

Just accept whatever peoples write in it, as "everything" is supported in matrix specs, apart from actual not allowed characters like whitespaces or so. Element even shows and joins to rooms with aliast containing ö or even 😀 so even that isn't generally an issue at least with rooms list. Should there be some other ineffiency in room alias handler (ad-hoc in text in chat or pill generator or whatever, those needs then fixing, would be kinda separate issue then).

@ptman All that it says relating is "human readable", which means different thing for different peoples in different geographies. Certainly not first 7-8 bits from ASCII table :)
