When editting older rtl documents, last character doubles

Hi there!

As I have mentioned in my previous topics that I have to play with rtl text a lot (mostly Arabic and Urdu). When I edit them sometimes later, and try to delete a character from a word, the preceding character repeats, it happens every time I do this. Very disturbing. I have to retype every Word I want to edit.

To provide an answer more information is needed. Please have a look at What information should I include in a question in addition to OS and LibreOffice version? - #4 by ROSt53 — Which language settings?

Sorry for that, I have included more information.
They are languages, Arabic and Urdu.

It also sometimes happens when you copy/paste an Arabic/Persian/Urdu text from a web page to a document. Or, sometimes when you copy/past such texts from a PDF to a document in Writer.
