Adobe Acrobat Reader MUI 23.003.20269 - corrupted characters

Hello,

after update Adobe Acrobat Reader MUI to the latest version 23.003.20269 we have issues with notes created in some PDF file with tool Fill & Sign.
Our default system language is 1029=Czech (čeština).

When I add to existing pdf document some note, after saving the file and re-opening we can see blank spaces, squares or "tofu symbols" instead of diacritics.

However it depends on method how you inserted the note.
When the note is handwritten, the result after saving is always corrupted.
When the note is pasted from another source e.g. from some website, only sometimes the result is corrupted after saving.

At previous version Adobe Acrobat Reader MUI 23.003.20244 the issue does not appear.

For comparisson I am attaching test files with some notes (handwritten and also with pasted text).
