How to turn off (stupid) warnings in GAWK (4.1.4)

For some reason, under certain circumstances, one of my scripts generates
this bogus error message:
gawk: ./zzz.awk:17: (FILENAME=- FNR=23) warning: Invalid multibyte data
detected. There may be a mismatch between your data and your locale.
Which messes up my output display. I can squelch this by the usual shell
hack (2>/dev/null), but I was wondering if there was a built-in way to turn
it off.
Note that TAWK has a "-w" command line option to turn off warnings, as well
as a WARNINGS built-in variable for more fine-grained control. Does GAWK
have anything similar?

some other encoding. Just a guess.
The best way to squelch that particular warning is with the -b, or --
characters-as-bytes option. That reads input files byte-by-byte, with ASCII
encoding.
Otherwise, you can redirect stderr to stdout, and filter the process output
to remove that particular warning. Or, with bash, redirect like 2>(filter).

Yes! Adding -b to the options list fixed the problem (made the error
message go away). It also, incidentally, fixed another migration issue in
the script output, so it is an unqualified good.
Every once in a while, the Usenet actually performs as intended. A
question is posted; a sensible, useful answer is given; everybody leaves
happy. Well done!
P.S. That all said, I'm still curious if there's a general way in GAWK
(i.e., not via the shell or filters or whatever) to squelch warnings.

OK - whatever that means. But thanks for posting.

Usenet is also intended for porn and insult contests.

HTH.

Try setting the variable LC_ALL=C in the shell (such as in the .bash_profile or .bashrc startup file). That may help. I also think setting the GNU awk variable BINMODE=3 inside a BEGIN{...} block may resolve this issue.

HTH.

Still missing the point.
I've tried to make it clear that I'm no longer talking about the specific
instance given. I'm talking about a general method to squelch warnings -
regardless of which topic they pertain to.
Like TAWK's "-w" option.

On Usenet, as in life, you get what you get.
