[bug-gawk] Using ENVIRON["LANG"] = "C" instead of --characters-as-bytes

[Hermann Peifer]

Hi again,

I thought that in gawk/master, I could use ENVIRON["LANG"] = "C" instead 
of --characters-as-bytes, in analogy to changing the time zone via 
ENVIRON["TZ"] = "UTC". I do however always end up with the lint warning: 
Invalid multibyte data detected. There may be a mismatch between your 
data and your locale.

Is this a feature ?

# Some code snippet which doesn't work as epxected
BEGIN {
        # Try to simulate --characters-as-bytes
        ENVIRON["LC_ALL"] = "C"
        ENVIRON["LANG"] = "C"
}
