Description:
The 'Find' function in LibreOffice 7.3 doesn't distinguish between នាម់ and នើម.

Steps to Reproduce:
1. Create a new text document in LibreOffice Writer
2. Copy this sample text for testing:
រានោកកាដាច់អាហាឆោរុស ម៝ត់អ្វាញ់លែៈគែសពែនាម់ ពាង់នទ្រាប់នាវញេតឆោងក្វ៝ង់ អ៝ន់មាទឹងលែៈកោរាញ ទឹងលែៈឞូនុយ្សនទ្រ៝ង់ក្វ៝ង់អីឆើមកើលជានការមាពាង់នើម នអ៝ប់មាមពោលកោរាញតាហែនផូងពើឆី នទ្រែលមាផូងមេដី នអ៝ប់មាមពោលនទ្រ៝ង់ក្វ៝ង់ នទ្រែលមាមពោលកោរាញក្វ៝ង់តាៈឞើសទឹងលែៈឞ្រីអីពាង់ម៝ត់អ្វាញ់នៃ គុឞើសនាប់ពាង់ទាទេដ៝ង់។
3. Do separate searches for the terms នាម់ and នើម.

Actual Results:
Searching for នាម់ finds នាម់ and នើម (2 hits).
Searching for នើម finds នាម់ and នើម (2 hits).

Expected Results:
Searching for នាម់ should only find នាម់ (1 hit).
Searching for នើម should only find នើម (1 hit).

Reproducible: Always

For me, it only happens when "diacritic-sensitive" is unchecked in the Find & Replace dialog, in which case, it tries to find also Unicode combining marks. I don't know if the characters in question form such marks, though. But still, test with "diacritic-sensitive" checked.

Confirm with the STR when using the Find bar, i.e. by <Ctrl>+F launch.

However, the Find bar <ctrl>+F does not set the 'diacritic sensitive' mode for searches.

Using the full "Find and Replace" dialog <ctrl>+H where 'diacritic sensitive' is set by default in the "Other options" section--it in general works best for CTL and CJK search use. 

IHMO => NAB as the Khmer script's vowel signs are handled similar to combining diacritics requiring the use of the more functional Find and Replace dialog.

I don't see any objections, so let's close
