tests: Tests could return UNRESOLVED on non-English Windows set to non UTF-8 encoding

[statementreply]

Describe the bug

I got the following output when running stl-lit.py

stl-lit.py: G:\STL\tests\utils\stl\test\format.py:225: warning: 'utf-8' codec can't decode byte 0xc3 in position 14: invalid continuation byte
UNRESOLVED: std :: tests/GH_000935_complex_sqrt:23 (17 of 29)

STL/tests/utils/stl/util.py

Lines 120 to 122 in 5be7d49

	# Ensure the resulting output is always of string type.
	out = out.decode()
	err = err.decode()

out.decode() fails because its encoding isn't UTF-8.

If you will enter chcp 1252 then rerun tests and they will run fine.
the UNRESOLVED disappeared for me...
