What this PR does

Improved handling of non-ASCII characters in transcript printing and JSON output from yt command

• Updated print(transcript) to handle non-ASCII characters correctly.
• Modified print statements to use ensure_ascii=False in json.dumps for correct display of non-ASCII characters.
• Implemented exception handling to manage potential UnicodeEncodeErrors, ensuring fallback encoding to avoid garbled text.

This change enhances the readability of outputs containing non-ASCII characters and addresses potential encoding issues across different environments.
