What ᵁ means
In UPA, it marks an extremely brief vowel or transition. The Uralic Phonetic Alphabet (UPA) is a way to write pronunciation, especially in Uralic languages. E. N. Setälä first published it in 1901 to record and compare speech sounds, sound patterns, and word histories, including reconstructed forms.
In this system, raised letters mark very short sounds; subscript letters mark co-articulation (two speech sounds produced together), and turned letters mark reduced sounds (sounds pronounced less fully). The UPA was modified in the 1970s, so follow the convention used by the transcription in front of you. To compare it with the International Phonetic Alphabet (IPA), another system for writing speech sounds, consult the source’s key instead of converting by shape alone.
How do I type ᵁ?
On the Finnish UPA/SUT layout, press AltGr + Shift + U. The shortcut enters the capital-form superscript; an ordinary U key enters U. This combination belongs to that layout, so other keyboards may differ.
Extended phonetic characters rely on font support. A fallback font can make them hard to distinguish, so check the font before treating an odd-looking form as a different character.
Technical and academic: its raised position carries a phonetic value in UPA transcription.
In ordinary text, it may be read as a phonetic modifier rather than decoration.

1Why does ᵁ show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
