What 𞁒 means
It marks a sound group when context hides the differences.
In one Bulgarian dialect study, it sits beneath Cyrillic п (the p sound) for a group including p and b, whose distinction can disappear in context.
Serbian dialectologists used Cyrillic superscripts and subscripts for stronger or weaker vowel values by 1905. A 2007 Bulgarian study of speech sounds uses this subscript letter for a sound group.

Read its subscript position as notation, not as a free-standing Cyrillic б.
