New submission from Michael Osipov <1983-01...@gmx.net>:
Running from 3.7 branch on HP-UX 11.31 ia64, 32 bit, big endian.
The test output is:

I tried to understand the issue, but my Python knowledge is too low, especially
I do not understand by a byte array "arg = 'h\xe9\u20ac'.encode('utf-8')" is
passed as one arg to the forked process.
I highly assume that this is related to the non-standard, default character
encoding on HP-UX: https://en.wikipedia.org/wiki/HP_Roman#HP_Roman-8 (roman8).
A stupid 8 bit encoding. The very same snippet on FreeBSD says:
> $ LC_ALL=C python3.6 test_utf8.py
> US-ASCII:[]
Willing to test and modify if someone tells what to do.
