That hangs as well, and I found out why: Gawk waits for input.  (I
don't know why this doesn't work as you intended, seems like another
incompatibility in MSYS Bash.)  To fix, replace this line

   print_at_sign='{print substr("'$cent_sign'@", 2)}'

with this:

   print_at_sign='BEGIN {print substr("'$cent_sign'@", 2)}'

and then even your previous version works.

Sorry for my imperfect debugging, there are too many potentially
problematic constructs in this script, and it's not easy to understand
what exactly misfires, especially when Bash shows me corrupted
non-ASCII strings.

Thanks.
