"\par" and "\\" haven't been cleaned will cause some issues.

"\par" and "\" haven't been cleaned will cause some issues.
This will cause some small unexcepted behavior of my grammar check tool.
For example, here is a cleaned code fragment generated by this tool.

Title \\

Due to this sentence ends with a strange symbol. My grammar checker(Grammarly) will not check this sentence in a proper way. Hope for fix this bug.

This bug only appears when the strange signature follows the sentence without any other character.
