I didn't mean to keep this private, just hit the wrong reply button.
But Markus is right about the fact that this is one of the hundreds of
editorial corrections that we made to the code charts for Unicode 3.0 to
better match existing practice, reduce confusion, or simply to upgrade to
higher quality type faces.
In the particular case, we did not take lightly the decision to fix these,
since scientists and engineers do need to have an unambiguous relation
between code and shape - they are not stylistic, but semantic variations in
Our own research revealed that ISO/IEC 8859-7 (Greek), the IBM registry of
code pages, the Microsoft Windows code page, etc. all map to U+03C6.
Correspondingly, this form has to be the one in common modern use, and the
font designers (with isolated exceptions) have followed suit.
Because swapping the glyphs in this instance matches overwhelming existing
practice, there should be little impact, but long-term much reduced
confusion, on which code to use for what.
