    Can anyone clarify this one:
    In Microsoft page here :
    says Malayalam chillu glyphs are formed when inputting
    (consonant)+(virama). Can I use another formation for chillus, I
    want to use (consonant)+(virama)+(ZWJ) any problem?
    And any problem, If I am am giving ligature formation in this
    in OpenType tables?
