Indeed, that's what JDK's javadoc seems to be saying.
The only change in jdk 1.5 was methods that take int as an argument
instead of char.
Reading the documentation of isWhitespace I realized that it DOES
include all unicode space characters!
And in addition to that it includes the standard ASCII whitespace
characters because they are not included in the unicode
space characters.
But for some unknown reason it explicitly decides to excude non-breaking
space from whitespace characters.
And for that I have not been able to find any reason.
Maybe they think that there is a consensus on not considering
non-breaking space as whitespace?
But it does not seem so widespread because unicode thinks about it
differently...
I would add the non-breaking space to H2's whitespace, because if it
looks like whitespace it should be whitespace ... right?

FYI: Character.isSpaceChar(char) has been around since the time
isWhitespace(char) was added. The only thing that's new is the
isSpaceChar(int) method.

It turns out that isWhitespace(..) is a legacy method and does not
consider nbsp as a whitespace character
(which it most certainly is according to unicode standard).
In Java 1.5 a new method was defined in the character class
isSpaceChar(..)
that properly recognizes all unicode space characters.
And isWhitespace was left as is for backward compatibility.

Hi,
What is the exact Unicode character code? The parser uses:
if (c<= ' ' || Character.isWhitespace(c)) {
// whitespace
}
Character.isWhitespace is supposed to return true for a non-breaking
space.

Thomas
