Hi,

[[:space:]] includes the following unicode character.
http://www.fileformat.info/info/unicode/char/00a0/index.htm

$ echo 'a b' | grep 'a[[:space:]]b'
a b
$ echo 'a b'|xxd
00000000: 61c2 a062 0a                             a..b.

Where is this info documented for grep?

Are these all the possible white space characters?
