When typing comments, it's useful to use the "@" system to alert a user to a comment (and also to make it clear to a 3rd party who you are addressing a comment to, as comments have no "thread-like" structure here). For example, typing "@MatthewDaws" would make it clear a comment was aimed at myself.
Some users have usernames using non-Latin based characters, which is definely all to the good of trying to make MO reflect the whole world, and not just the English speaking bit of it. However, this seems to make it very difficult to interact with the "@" system, because my (English) keyboard doesn't allow me to type these different characters.
Is there an "official" way to use the "@" system here?
I have had some luck by highlighting and copying the username, and then typing "@", pasting, and then backspacing until the "auto-suggest" system selects the correct username. But that feels a bit clunky...
