khmer-normalizer

This module normalizes Khmer text according to the proposed normal encoding structure at https://www.unicode.org/L2/L2022/22290-khmer-encoding.pdf.

It does not attempt to identify faulty text, merely to ensure that two strings that would have rendered the same are output as the same string.

A live online version is available at https://convert.ភាសាខ្មែរ.com/ (see https://ភាសាខ្មែរ.com for related tools).

Example

ខែ្មរ is corrected to ខ្មែរ:

• Input: ខ U+1781 ែ U+17C2 ្ U+17D2 ម U+1798 រ U+179A
• Output: ខ U+1781 ្ U+17D2 ម U+1798 ែ U+17C2 រ U+179A
