Plugtest 2021: MEC013: Schemas have non-valid characters preventing the validation

Some schemas have invalid characters in them preventing the validation to go through.

Example of error: 15:52:11.452 TRACE Arguments: [ 'UserList.schema.json' | {'userList': {'resourceURL': 'http://3.84.255.29/simon/location/v2/queries/users'}} ] **15:52:11.454 FAIL UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb0 in position 3615: invalid start byte ** 15:52:11.457 DEBUG Traceback (most recent call last): File "/usr/local/lib/python3.6/site-packages/JSONSchemaLibrary/init.py", line 31, in validate_json schema = json.loads(open('{}/{}'.format(self.schema_location, schema_filename)).read()) File "/usr/local/lib/python3.6/codecs.py", line 321, in decode (result, consumed) = self._buffer_decode(data, self.errors, final)

This error comes from the schema file position 3615 which has a non valid character: Location latitude, expressed in the range -90� to +90�. Cardinality greater than one only if "shape" equals 7.

The error is not visible in the json file, but if looking at the file in the raw format... all there characters can be seen. They are replacing some sort of 'degree' symbol maybe or something else. The same thing has been seen when using apostophes.. so as: Structure with attributes relating to the target entity�s velocity, as defined in [14].
