Sure, although the code should work even plain POSIX awk, as there 
should be no need to assume such a GNU extension when bootstrapping.  
That is, the script could support either:

1. POSIX awk with multibyte OS support, with proper UTF-8 checking from 
OS libraries; or

2. GNU awk 4 (2012) or later, with nearly-as-good UTF-8 checking 
hand-coded into the script; or

3. Traditional awk without UTF-8 checking.

Currently the script supports (1) and (3) but someone could add support 
for (2).
