header encoding issue???

[BrightArgo]

receiving the following error:

venv/lib64/python3.11/site-packages/httpx/_utils.py", line 53, in normalize_header_value
return value.encode(encoding or "ascii")
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
UnicodeEncodeError: 'ascii' codec can't encode character '\u2018' in position 7: ordinal not in range(128)

I am not directly calling the httpx module, it is being referenced by gradio which in turns passes on the request headers via the browser. I believe that is where the breakdown occurs. My understanding of the code and from forums is that by default UTF-8 should be the encoding utilized. If this is the case, I am unclear why httpx falls back to using ascii. I am running Python 3.11 on Oracle Linux 8 and have doublechecked all my environment variables. My code works fine on my Mac. Happy to provide additional details.

Replaced ascii in _utils.py with UTF-8 and discovered the real issue related to header encoding.
