Sure it can. It operates on dchar. I don't know what you've done with std.uni,
but the way things have been laid out is that
std.ascii: Operates on dchars, doing ASCII operations, generally ignoring
anything that's not ASCII.
std.uni: Operates on dchars, doing Unicode operations. The operations are
generally the same as what you'd do with ASCII only with Unicode instead.
std.utf: Doing encoding related stuff with Unicode, so it operates on strings.
std.string: Operates on strings (almost always using Unicode)
So, with how it's been, std.uni would only be operating on dchars, and putting
a function in there which operated on strings wouldn't make any sense. Maybe
that doesn't work if you've done a bunch of grapheme stuff, and things will
have to be adjusted, but it would be a definite shift to put anything in
std.uni which operated on strings, and I think that it would need some definite
justification (and there's a good chance that I'd be inclined to argue that it
should still go in std.string, possibly using some internal modules if
necessary).
But clearly I need to take the time to take a look at what you've actually
done (I keep meaning to but haven't gotten around to it yet). It had been my
impression that what you were doing was primarily a matter of improving the
implementation, but it sounds like you're doing something beyond that.
