close 15440
thanks
I've pushed my grep patches, but chose to omit 4 multibyte space
characters from the list in the test, since each of those would
provoke a failure on recent glibc-based systems (fedora 19). That
seems to be due to errors in glibc's UTF-8 multibyte flags (wrong
whitespace bit) for those characters.
Arnold, I tried your latest gawk on a Fedora 19 system, and see the
same failure for those four characters, e.g.,
$ printf '\xc2\xa0\n' | LANG=en_US.UTF-8 LC_ALL=en_US.UTF-8 ./gawk
'/[[:space:]]/'|wc -c
