'ascii' codec can't encode character '”' in position 0: ordinal not in range(128)

Newbie issue!

After launching the app via:
$ PYTHONUTF8=1 adk web --port 8000
navigating to the browser and entering any text in the Message box on the right pane results in the following response:

 'ascii' codec can't encode character '”' in position 0: ordinal not in range(128)

Tried several basic attempts at resolution, but all failed:

• script declaration:

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

• environment variable declaration:

PYTHONUTF8=1 adk web --port 8000

• EXPORT statements:

export PYTHONUTF8=1

export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8

Nothing works, the error message persists. Locale is correctly set to "en_US.UTF-8" as confirmed by locale command output.

Any suggestions? Thanks.

Regards.

P.S.
