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 0
