Bug 143734

Description:
Calc in LibreOffice version 7.0.6.2 on Ubuntu 20.10.  UK keyboard and locale.

Symptom:
This is a text-entry or saving problem.
I save some commands for my Linux server in a spreadsheet which contains the " character on most lines.  Bizarrely, random lines will have only the opening " changed to a different encoding of " which looks like this: “ (curlier but not set to italic).  It can sometimes be re-entered correctly and then changes again upon saving.

Use case and effect:
This broke a lot of my recovery scripts (when I paste into terminal with Shift+Ctrl+v) and led me on a merry goose chase including reinstalling my OS because I thought rsync was broken because it just gave a nondescript > prompt.  I also worried I might be hacked.  I recovered my system from live USB.  It took an eagle eye to see this imperceptible change in a wall of code.

Many sysadmins keep short scripts in a spreadsheet.  This happens for a couple of years now and I never figured out what was going on.

Corollary:
I have also had problems in Geany where _ underscores went missing and that made debugging my mail server a nightmare.  I don't know if the two are related, but these past couple of years I have seen more occurrences of text entry getting mangled by programs.  This email is disposable so will only check messages within bugzilla.  That bug has a workaround of changing the default font.

Thank you for all your great efforts in making this software.  Filed with the intention to help.

Steps to Reproduce:
1. Make a calc sheet with a one-liner rsync script for example containing an opening and closing "" e.g. for a directory that has to escape spaces in the path.
2. Save the file.
3. Reopen the file and try copying and pasting the cell with the script.  Edit it for a new path and then edit another cell.  Witness the opening " change in the original.

Actual Results:
Random lines will have the opening " change to curly “ which breaks a shell when you try to paste and run the script.

Expected Results:
My " should stay as " and not be changed to “.


Reproducible: Sometimes
