This character is a Currency Symbol and is commonly used, that is, in no specific script.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written as end of a European number, e.g., a currency symbol, from left to right. When changing direction it is not mirrored. U+20AD prohibits a line break after it, if it is followed by a number. The glyph can be confused with one other glyph.
The Wikipedia has the following information about this codepoint:
The kip (Lao: ກີບ, romanized: kib; code: LAK; sign: ₭ or ₭N; French: kip; officially: ເງີນກີບລາວ, lit. "currency Lao kip") is the currency of Laos since 1955. Historically, one kip was divided into 100 att (ອັດ) which are no longer in regular use. The term derives from ກີບ kì:p, a Lao word meaning "ingot."
