Issue

noto-khmer-bug

The diacritic khmer sign muusikatoan is incorrectly appearing below the khmer letter mo when it is followed by a character carrying the khmer vowel sign i. This issue is seen when any consonant with the vowel modifier ៉ plus vowel sign េ and then followed by រ with either ិ, ី, ឹ or ឺ.

Expected result is displayed in screenshot above. The first the examples are shown in DaunPenh, Khmer MN, and Arial Unicode MS fonts. All of those examples render this correctly.

@marekjez86 in using these updated fonts I find that the version number was not changed so these fonts with the merged fix are the same 2.001 version as before. Is that expected for a bug fix like this? Thanks
