Character(s) replacement in editor

[ClementGre]

Have you read a contributing guide?

• I have read CONTRIBUTING.md
• I have searched the existing requests and didn't find any that were similar
• I have considered creating a pull request instead and want to proceed

Clear and concise description of the problem

When typing (r), it is replaced by ®. This is particularly annoying when typing math functions such as f(r).

Suggested solution

Either disable all characters replacement, or add in the settings a way to choose which replacements to use.

Alternative

I haven't found any alternative, even when copying (r) to a page from the clipboard, it will be replaced by ®

Additional context

Somewhat related to #1110. Maybe instead of completely disabling it could show a popup preview that you can hit enter to accept or any other key to decline. Although having the ability to turn these replacements on and off would be useful too
