Is there a way to sanitize values from non-ASCII characters in the rich text editor?

[tpostolyuk]

Hi,
Is there currently a built-in or recommended way to sanitize input values to remove or filter out non-ASCII characters when users enter content into the rich text editor?

I'm looking to ensure the content remains strictly within the ASCII character set (e.g. for compatibility or downstream processing reasons).
If no such option exists yet, would you consider adding support for configurable input sanitization or transformation hooks?

Thanks in advance!
