Using wcwidth.awk with gawk and a UTF-8 locale fails:

      $ make                                                                                                                                                                
      gawk
      - sanity check: gawk: wcwidth.awk:104: error: Invalid collation character: /^([-][-][ -~]*)+/

It does seem to work with mawk, or with gawk with the C locale though.

Commenting out the lines 104-112 solves the problem, but I'm not sure what it impacts.

This is strange. I'm guessing something in GAWK changed since the error appears with older versions of this code. Until I can figure this out, deleting those lines won't impact functionality. That block is purely a performance optimization that doesn't impact the output which is why the tests still pass.

Thanks. I'll leave it commented then, as I'm not sure I'll have time to look into it in the foreseeable future.
