[Windows] PSUTIL service lookup having unicode issue with special characters - (Č) to be specific

[MrPippin66]

Summary

• OS: Windows Server
• Architecture: x86
• Psutil version: 6.1.1
• Python version: 3.6.8
• Type: core

Description

From Nagios NCPA.

There is apparent Unicode issue with the service status check for psutil.

Service names that have a non-standard UTF character will fail a lookup in service status:

File "psutil_pswindows.py", line 628, in status
File "psutil_pswindows.py", line 558, in _query_status
File "contextlib.py", line 158, in exit
File "psutil_pswindows.py", line 583, in _wrap_exceptions
psutil.NoSuchProcess: service 'ČSOB Business Connector' does not exist (name='ČSOB Business Connector')

I note that PSUTIL in the service iteration is doing a Unicode conversion.

PyUnicode_FromWideChar(*)

But...when looking up a specific service, it's not doing the transverse, which may be what causes this problem

    def description(self):
        """Service long description."""
        return cext.winservice_query_descr(self.name())

AKA, converting self.name() via PyUnicode_AsWideChar(*) back to wchar format.
