Description Roozbeh Pournader 2013-11-23 21:17:43 UTC

The sequence U+1004,U+103A,U+1039,U+104E (NGA + ASAT + VIRAMA + AFOREMENTIONED) is rendered with a dotted circle in HarfBuzz, but it is valid according to UTN #11:

"One of the significant changes between Unicode 4 and Unicode 5.1 was the change in spelling of lagaun changed from U+104E to U+104E U+1004 U+103A U+1038. This is to facilitate an alternative spelling of lagaun of U+1004 U+103A U+1039 U+104E. This change results in a subtle change of behaviour for U+104E from being a complete punctuation symbol with corresponding predefined line breaking 
behaviour, to being just another character that needs algorithmic analysis both for segmentation and for sorting."

    [myanmar] Mark U+104E MYANMAR SYMBOL AFOREMENTIONED as Consonant
    
    The spec and Uniscribe treat it as consonant in the grammar, but
    it's not in IndicSyllableCategory.txt, so fix up.
    
    Test sequence: U+1004,U+103A,U+1039,U+104E
