Well, actually, that's not _quite_ true. Changing the default character
encoding *does* require VM support. And, doing so *will* introduce a certain
amount of incompatibility. The point I was making is that "our daily use of
fonts" is not necessarily affected (e.g., changing the default encoding does
not necessarily affect whether you can use any of the fonts currently in
Squeak).

The reason why it introduces a certain amount of incompatibility is that the
character sets are not to 100% compatible. Some glyphs appear in some of
them, others don't. If there is no equivalent for a certain glyph in some
font you will have some incompatibility. Yet, for the vast amount of
characters in the fonts this will not be an issue (the only ones I can think
about where this might cause a problem are 'decorative glyphs' such as
bullets) since the glyphs are "reasonably compatible" across the major
encoding families for latin fonts.

I also think that changing the default character encoding would be very
worthwhile. As it is, we use a default encoding which is no longer actively
supported (e.g., even Macs essentially emulate it today) and that means that
as we are moving towards different fonts we will have more and more "holes"
in the character sets - glyphs that are not in Mac Roman but not in others
and glyphs that are in others and not in Mac Roman will have to be left out.

Cheers,
  - Andreas
