How search quotation mark character by find and replace?

Hello. I’d like to know how to seach the quotation mark character in find and replace. You can use the CHAR function in formulas when using functions, but I don’t know how to do it in find and replace. I think I should use regular expressions, but I don’t know how.
My LibreOffice version is 7.2.7.2
Regards

Quotation mark characters are ordinary characters which you can find with or without RegEx enabled.
If there are problems: “Typographic” quotation marks won’t be found when searching for straight ones.

Thanks for responding so quickly. I don’t know what you mean by problems. Do you mean problems with the LibreOffice configuration? Unless I checked it incorrectly, the Autocorrect and Regional Options section is fine. Anyway, thanks for the reply, and I’ll keep looking for a solution. Thanks.

No. I just wanted to point you to a possible complication with special settings or uncommon characters used as quotation marks.
Generally I recommend to omit AutoCorrect what I rather see as AutoMessup.
If quotation marks must be "left(open)" or "right(close)" like parentheses I suggest to use the French version: «- - -». We should abandon “national” stupidities.
