This character is a Nonspacing Mark and is mainly used in the Tamil script. The character is also known as pulli.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Nonspacing Mark. When changing direction it is not mirrored. U+0BCD prohibits a line break before it. The glyph can be confused with one other glyph.
The Wikipedia has the following information about this codepoint:
Virama (Sanskrit: विराम/हलन्त, romanized: virāma/halanta ्) is a Sanskrit phonological concept to suppress the inherent vowel that otherwise occurs with every consonant letter, commonly used as a generic term for a codepoint in Unicode, representing either
halanta, hasanta or explicit virāma, a diacritic in many Brahmic scripts, including the Devanagari and Bengali scripts, or
saṃyuktākṣara (Sanskrit: संयुक्ताक्षर) or implicit virama, a conjunct consonant or ligature.
Unicode schemes of scripts writing Mainland Southeast Asia languages, such as that of Burmese script and of Tibetan script, generally do not group the two functions together.
