That is true. It doesn't have anything to do with Unicode however, as I
think your post implied.

Speaking of which, I wonder if there's a database name record out there
at all containing someone with a retroflex click in his name. And if
it's recorded as the exclamation mark, or U+01C3 ;P

It Should Be Able To.

I think at least oniguruma can do this sort of "industrial-strength"
processing, no idea about the current engine.

Speaking of which, is there a Oniguruma 1.8 backport (?) that you could
use as an add-on regexp engine? (I think currently you can use it as a
drop-in replacement if you built Ruby from source, I was thinking of a
more orthogonal way of using the Shiny Features. Where orthogonal really
means from a binary gem.)
