Yes, capital Omega is mapped to lower case Omega, but why?
I can understand that "A" has to be mapped to "a" to stop multiple
registrations of the same name with different capitalizations. But
why extend that "solution" to other code points? Clearly, the two
glyphs (‡ v. w) are different enough to be noticed as being different
-- so, the rational for excluding one (i.e., Character Equivalence
Mapping) in favor of the other must have some grounds. But, what?
Furthermore, if one had to map one code point to another, then why
didn't it go the other way? In other words, why wasn't the capital
Omega kept and the lower case mapped to the upper case. After all,
the capital Omega (‡) looks considerably different than all other
glyphs -- where as the lower case Omega looks like a common to many
languages "w". In addition, I would bet that the upper case Omega has
better global recognition than its lower case brother. So, what's the
point of Character Equivalence Mapping in this case?
