The Wikipedia has the following information about this codepoint:

Chandrabindu (IAST: candrabindu, lit. 'moon dot' in Sanskrit) is a diacritic sign with the form of a dot inside the lower half of a circle. It is used in the Devanagari (ँ), Bengali-Assamese (ঁ), Gujarati (ઁ), Odia (ଁ), Telugu (ఁ), Javanese ( ꦀ) and other scripts.
It usually means that the previous vowel is nasalized.
In Hindi, it is replaced in writing by anusvara when it is written above a consonant that carries a vowel symbol that extends above the top line.
In Classical Sanskrit, it seems to occur only over a lla conjunct consonant, to show that it is pronounced as a nasalized double l, which occurs if -nl- have become assimilated in sandhi.
In Vedic Sanskrit, it is used instead of anusvara to represent the sound anunasika when the next word starts with a vowel. It usually occurs where in earlier times a word ended in -ans.
