Yes. When I've made websites using the PUA section for Klingon, even
though my Unicode font contains the right glyphs there, it's unreadable
because some of those codepoints overlap some Adobe or Apple characters,
and my browser in its wisdom decides that Adobe wins. So some of the
characters show right, and some show (r) signs and suchlike.

(We're now *trying* to do more data interchange in Klingon characters,
the lack of which is what held Klingon back from encoding in the first
place... but we *can't* because we're not encoded! What a catch-22!)
