How Can I Recover Default Character Encoding Functionality in Python?

Recovering the Default Character Encoding Functionality in Python

Questioners often encounter difficulties when working with character encoding in Python, particularly due to "can't encode" and "can't decode" errors encountered when executing applications from the console. Within Eclipse PyDev IDE, these issues are easily resolved by the default UTF-8 character encoding setting.

However, attempts to set the default encoding programmatically through sys.setdefaultencoding are met with failure, as Python intentionally removes this function during startup. This raises the question: what practical solutions are available to address this issue?

Reload Method

A workaround solution exists, but it must be used with caution due to its potentially disruptive nature:

import sys
# sys.setdefaultencoding() does not exist, here!
reload(sys)  # Reload does the trick!
sys.setdefaultencoding('UTF8')

Note: In Python 3.4 and later, the reload() function is located in the importlib library.

By reloading the sys module, the setdefaultencoding() function is restored, allowing for the default encoding to be modified to UTF8. However, this approach should be used judiciously as it can impact code that assumes ASCII as the default character encoding. Third-party code, in particular, poses a significant risk, as modifications may be impractical or pose risks.

It is important to note that this workaround is not supported in Python 3.9 and beyond. Therefore, alternative solutions should be explored for newer Python versions.
