Ok. that's related to
http://developer.postgresql.org/cvsweb.cgi/pgsql/contrib/tsearch2/wordparser/parser.c.diff?r1=1.11;r2=1.12;f=h
commit. Thomas pointed that it can be non-breakable space (0xa0) and that commit
assumes any character with C locale and multibyte encoding and > 0x7f is alpha.
To check theory, pls, apply attached patch.
If so, I'm confused, we can not assume that 0xa0 is a space symbol in any
multibyte encoding, even in Windows.
