Re: Unicode character \u2102

[Uncle George <gatgul@voicenet.com>]

The 1.2 specification for Character.isLowerCase() appears to have 2
specifications. Also one might also read that all the "L1" characters are
"considered to be lowercase"
1) is the "L1" in the unicode 2.0 character set.
2) The other soecification that specifically excludes the \u2000 <=>
\u2fff range.

The Character.isUpperCase() does not have any Unicode character
'category" specification at all.

It is not yet, to me, what is/isnot really true/false for any of the
Character methods. Searching......
