U+028D Latin Small Letter Turned W

The Wikipedia has the following information about this codepoint:

The voiceless labial–velar fricative is a type of consonantal sound, used in spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʍ⟩.

Some linguists posit voiceless approximants distinct from voiceless fricatives. To them, English /ʍ/ is an approximant [w̥], a labialized glottal fricative [hʷ] or an [hw] sequence, not a velar fricative, though Scots /ʍ/ has been described as a velar fricative, especially in older Scots, where it was [xw]. Other linguists believe that a "voiceless approximant" is a contradiction in terms, and so [w̥] must be the same as [xʷ]. Ladefoged and Maddieson were unable to confirm that any language has fricatives produced at two places of articulation, like labial and velar. They conclude that "if it is a fricative, it is better described as a voiceless labialized velar fricative".
