Description dubiousjim 2012-04-19 11:57:45 UTC 
BusyBox 1.19.3, built against uClibc 0.9.32, on i686 Linux

This works properly:
$ printf 'abc!def' | awk -v FS='\x21' '{print $1}'
abc

This should work the same way, but doesn't:
$ printf 'abc!def' | awk -F'\x21' '{print $1}'
abc!def

The same issue affects `awk -F'\t' ...` and so on.
