[Stuart] I've got to question this specific line of reasoning. If your
criterion for distinctiveness is "same pixels on the screen", then, at
best, that's an issue to take up with font designers. But that

Consider this. U+0391 (&#913;) is a capital Greek alpha, which in
virtually every font is visually indistinguishable from &#65; the
English letter A. Here's a simple HTML document, save it, load it in a
browser, and see for yourself:

<HTML><BODY>&#65;&#913;</BODY></HTML>

These are distinct code points, hence different characters, even if
similar or identical glyphs are used. I don't get how this becomes a
Windows (or any other operating system-specific) problem. If the letter
'O' and numeral '0' are visually indistinct on my computer, in whatever
font I happen to use, should the file system prevent me from using one
of these characters? I don't think so.

Cheers,
Stuart
