Update check_ncpa.py to Decode latin-1

[maxwbot]

Some error with ptbr entry. Solved by adding correct Decoding Latin-1.

Hi @maxwbot, thanks for the PR!

Can you let us know 1) what endpoint you were trying to use, 2) what environment NCPA is installed in, and 3) what error you were seeing? I'm not very experienced with the NCPA project, but I would be surprised if NCPA was intentionally serving anything other than UTF-8. What would be a lot less surprising is if some endpoint was taking data (especially on Windows, but possibly on other devices) and failing to properly re-encode it. If this is happening, we'd probably want to fix the endpoint, instead of having check_ncpa.py force everything to be re-interpreted as Latin-1 encoding.

Hi @sawolf ,
Do you have the ncpa 3 beta repository? (NCPA_2 uses the obsolete version of python 2.7.. the new NCPA_3 uses python 3?)

The problem lies in the coding:
for service in psutil.win_service_iter(): name = service.name()
