This character is a Other Letter and is mainly used in the Hiragana script.
The glyph is not a composition. Its East Asian Width is wide. In bidirectional text it is written from left to right. When changing direction it is not mirrored. U+3080 offers a line break opportunity at its position, except in some numeric contexts.
The Wikipedia has the following information about this codepoint:
む, in hiragana, or ム in katakana, is one of the Japanese kana, which each represent one mora. The hiragana is written with three strokes, while the katakana is written with two. Both represent [mɯ].
In older Japanese texts until the spelling reforms of 1900, む was also used to transcribe the nasalised [ɴ]. Since the reforms, it is replaced in such positions with ん.
In the Ainu language, ム can be written as small ㇺ, which represents a final m sound. This, along with other extended katakana, was developed by Japanese linguists to represent Ainu sounds that do not exist in standard Japanese katakana.
