What's yucky about that is that they will start producing Unicode documents
with 0x80 as the euro glyph and spreading them around.

I've already had to put code like this in our web browser:

      int decode_character_entity()
          if (p[0] == 'x' || p[0] == 'X')
              u = strtol(p, 16, NULL);
              u = atoi(p);
          if (u >= 0x80 && u <= 0x9F)
              u = cp1252_table[u-0x80];
to cope with all the web sites that contain things like "it&#133;s".

We really don't want to encourage that sort of thing. I haven't yet had
to put an equivalent bit of code in my UTF-8 or UCS-2 decoders, but I
wouldn't be surprised if I had to some time soon.

What's so hard about installing the euro patch anyway? Why give naive users
the opportunity to unknowingly do it wrong when it's easy to do it correctly?
