Digging a bit deeper, I see that the problem with hanging is not due
to Gawk, but instead due to 'printf': it doesn't produce the UTF-8
encoding of the percent sign, but some invalid sequence instead.

If I add an explicit

    cent_sign = "¢"

to the Awk part of the script (where the cent sign is UTF-8 encoded),
then the hook correctly processes log messages with UTF-8 encoded
non-ASCII letters and doesn't hang.  It doesn't use the [[:print:]]
alternative, though, probably because UTF-8 encoded characters are not
recognized as such, and a UTF-8 locale cannot be used on MS-Windows to
force that.
