           Summary: Failed to search Arabic text for a word if the Arabic
                    text is using "Arabic diacritics"
           Product: LibreOffice
           Version: 6.1.1.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium

Description:
(1) Quick background:
In Arabic writing system there is something called "Arabic diacritics"
https://en.wikipedia.org/wiki/Arabic_diacritics

Arabic diacritics have significant values at the sound level, meaning level,
and grammar level.


(2) The Bug:

If we write some arabic text using "Arabic diacritics" in LibreOffice Writer, 
then we tried to use find function in LibreOffice Writer to find any already
existing word, it fails to find it as if it is different word.

(3) Example for the bug: 

--> For example having these Arabic text:

بِسْمِ ٱللهِ ٱلرَّحْمٰنِ ٱلرَّحِيمِ

يَا أَيُّهَا النَّاسُ اتَّقُوا رَبَّكُمْ ۚ إِنَّ زَلْزَلَةَ السَّاعَةِ شَيْءٌ عَظِيمٌ (1) يَوْمَ تَرَوْنَهَا تَذْهَلُ كُلُّ مُرْضِعَةٍ
عَمَّا أَرْضَعَتْ وَتَضَعُ كُلُّ ذَاتِ حَمْلٍ حَمْلَهَا وَتَرَى النَّاسَ  سُكَارَىٰ وَمَا هُم بِسُكَارَىٰ وَلَٰكِنَّ عَذَابَ اللَّهِ
شَدِيدٌ


--> Then we try to search for the word:
الناس

--> Then it fails to find the word match although it is already existing more
than one time.


Steps to Reproduce:
1. Open LibreOffice Writer

2. Write Arabic text using "Arabic diacritics" 
(Or quickly you can copy & paste sample arabic text from:
https://en.wikipedia.org/wiki/Arabic_diacritics)

3. Press (Control + F) buttons to find text in the page

4. Write one arabic word from the ones in the written text but without "Arabic
diacritics". 



Actual Results:
The bug happens, and LibreOffice fails to find the word.


Expected Results:
LibreOffice should be able to find the existing word inside the text.



Reproducible: Always


User Profile Reset: No
