Details:

Steps to reproduce:
1. Set the editor encoding to some codepage that cannot encode all characters
(e.g. ISO-8859-6).
2. Open an existing file with e.g. only ASCII characters.
3. Add some characters that cannot be saved with the selected encoding (e.g.
"äöü") and save the file.
4. An error message is displayed and the existing file is overwritten with an
empty file.

In this case, the prior content of the file should be retained.

Also in light of bug #55306, it would be nice to leave the user the option to
save the file even if not all characters can be encoded.
