Scripting
Scripting is a super powerful tool for text manipulation. This feature is disabled by default, due to the complexity of these filters, as well as the additional resources that they may take up.
While the scope of these scripts are extremely limited, and several measures are put in place to ensure security and stability, these scripts are still very powerful, and you should never run code that you don't trust.
To learn more about these filters, you can view the example filters in this repository, or view the wiki.
