In the course of its adaptation to non-Indo-Aryan languages, the Burmese script has acquired some features that distinguish it from other Indic scripts. The killer, or virama, participates in some common constructions that would be clumsy to handle the way they would be in the other Indic scripts, so the control function of the virama is separated from the diacritic function of the killer. The virama, 0F4D is used to form conjunct consonants, while the killer, 0F52, is a simple diacritic and has no effect on character shaping. The killer is also combined with the VOWEL SIGN O (0F4B) to form the low level tone vowel “o.” When used this way, this symbol is known as hyei hto, or “thrust forward.”
