As an example, the user currently named ಠ_ಠ Won't
My request (for an admittedly tiny base - but of some consequence, considering who my example user above is) is that the auto-complete for @-replies also considers the user's first plain-ASCII-compatible character;

Well, that makes my request more weak, certainly. It simply would not cover such situations. (a space should never be considered, IMO, as that would needlessly pop up the auto complete when someone was merely trying to type an
I envision the most useful situation for this would be mobile users, where it might be a bit more complex to copy-paste the user's name and/or type in the 'special' characters.
