isLetter on Katakana marks

Hi,

I was testing the isLetter method in 1.1.3 on some Katakana characters
and found that the following characters were identified as letters:

\u30FC Katakana-Hiragana Prolonged Sound Mark
\u30FD Katakana Iteration Mark
\u30FE Katakana Voiced Iteration mark

This seems incorrect according to Java's explanation:

     * A character is considered to be a letter if and only if
     * it is specified to be a letter by the Unicode 2.0 standard
     * (category "Lu", "Ll", "Lt", "Lm", or "Lo" in the Unicode
     * specification data file).
     * Note that most ideographic characters are considered
     * to be letters (category "Lo") for this purpose.

Has anyone else noticed this?

Chuck
