Spurious glyphs in NotoSansMalayalam

NotoSansMalayalam is a font released by Google internationalization team under noto project. I was checking the glyphs of Malayalam and noted a number of spurious glyphs in the font

notosansml-unwantedglyphs

It is interesting because the font attempted to provide a minimal Malayalam font with reduced glyph set. While attempting that about 10% of the glyphs are either non-existing Malayalam glyphs(Glyphs with dot under consonants) or rarely used glyphs(Glyphs with U+0D62 MALAYALAM VOWEL SIGN VOCALIC L)

Bug filed. It was learned that the last set of glyphs with dots above and below are for Carnatic music notations. They are not defined by unicode, but font used a custom way of representing them with a ligature formed by U+0307.

    Reduced glyph set is probably not an objective of this font.

    1. Those are composite glyphs and hardy take up any space. At 59K for unhinted, Noto is one of the smallest fonts available today.
    2. Those dotted ones are required for writing music notes.

    Noto’s wants cover EVERY unicode character how obscure that may be.

  2. മലയാളം ചിലങ്ക വളരെ നന്നായിട്ടുണ്ട്. കൂടുതല്‍ മലയാളം ഫോണ്ടുകള്‍ ഉണ്ടാകാന്‍ ആശംസിക്കുന്നു. ്യ ഈ ചിഹ്നം ചില ubundu version -കളില്‍ യ് എന്നായി മാറുന്നു.
