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? http://jkorpela.fi/chars/spaces.html -- Regards, Peng
