But when replacing marked text with "\"

[nivaca]

Expected behavior

The selected text gets replaced with a "\".

Actual behavior

Smartparens completely changes my text and I cannot undo the changes.

Steps to reproduce the problem

In latex-mode, select a piece of text within curly braces. Type "\".

I second this bug report. It also happens with quotes when a region is active. Using ubuntu 20.04 linux.

I can reproduce this but for me it only happens if I also select an empty space in front of the word, otherwise it just erases the word and does nothing (not even inserting \)

I have the same problem with Emacs 28 on MacOS High Sierra.
This is very annoying as undo will not work properly in this case, so I have to remember the original text or find an old version of the file.

I can no longer reproduce this bug.

[temyurchenko]

I can still reproduce this bug (calling "" on a region just deletes the region). It should be solved with the new AUCTeX version and #1208 merged in.
