Dear Arnold,
thank you for kindful advice; out of two solutions the -b option worked
well.
LC_ALL=C, on the other hand, does not work because Termux does never
serve any other
locales than en_US.UTF-8.
Also thank you for pointing out my misunderstands about invokation;
the reason how env -i awk works is because it seems that AWK on Android
itself seemed
to be invoked.
Thank you for helping me.

Hi.
I'm not familiar with Termux. There should be no difference between
invocation of gawk as 'awk' or as something else, since gawk pays no
attention to argv[0]. (Unless the Termux guys modified the code.)
That said, it does look like a locale issue, since env -i clears the
environment,
forcing gawk to use the "C" locale.
You can use
LC_ALL=C gawk ...
as one way to get what you want. Another choice is to use gawk's -b
option, which forces gawk to treat characters as bytes.
Thanks,
Arnold

I am trying to let GAWK output every byte in range of 1--255,
but I
think I have found a bug.
To summarize, I have found it works when I invoke AWK, symbolic
link to
GAWK, under env -i,
and it's the only way I have ever found. I have never found the
way
when invoked as GAWK yet.
