UnicodeDecodeError: 'ascii' codec can't decode byte 0xb0 in position 0: ordinal not in range(128)

Question

```python

rm = pyvisa.ResourceManager("C:/Windows/System32/visa32.dll")
keithley_analyzer = rm.open_resource('GPIB0::17::INSTR')

visa address没错，但是open这句代码报错了，报错如下：
Traceback (most recent call last):
  File "E:\workspace\project\pythonProject3\main.py", line 46, in <module>
    keithley_analyzer = rm.open_resource(visa_address)
  File "E:\workspace\project\pythonProject3\venv\lib\site-packages\pyvisa\highlevel.py", line 3247, in open_resource
    info = self.resource_info(resource_name, extended=True)
  File "E:\workspace\project\pythonProject3\venv\lib\site-packages\pyvisa\highlevel.py", line 3174, in resource_info
    ret, err = self.visalib.parse_resource_extended(self.session, resource_name)
  File "E:\workspace\project\pythonProject3\venv\lib\site-packages\pyvisa\ctwrapper\functions.py", line 2087, in parse_resource_extended

    buffer_to_text(val)

    return buf.value.decode("ascii")
