How to Handle Non-Printable Characters in HTTP Responses on Windows Consoles?

UnicodeEncodeError: 'charmap' codec can't encode character maps to

Problem:

Attempting to print HTTP response data containing non-printable characters in the Windows console results in an error due to encoding issues.

Details:

• Default encoding in Windows console (Code Page 850) differs from the GUIs encoding (Code Page 1252), leading to misinterpretation of characters.
• Code snippet is used for debugging and includes inappropriate decoding and encoding cycles.
• Solution seeks code robustness against varying output interface encodings and accurate character representation.

Solution:

Method 1: Change Output Encoding

Configure the output encoding to consistently use UTF-8, ensuring proper character representation regardless of the interface encoding.

Method 2: Use a Custom Print Function

Utilize a custom print function to properly encode the output based on the target charset. This helps avoid modifying the entire code base.

Method 3: Reset Output Encoding Globally

Alter the I/O encoding function to globally set the output encoding to the desired value, such as Code Page 850. This is achieved through the codecs.getwriter method.

Additional Considerations:

• Input data must be correctly convertible into Unicode to prevent encoding issues.
• The specified encoding may vary depending on the requirements and encoding capabilities of the output interface.
• Encoding specific characters may involve additional considerations or specialized handling.
