Beta

The letter Β had the largest number of highly divergent local forms.

In the International Phonetic Alphabet, Greek minuscule beta denotes a voiced bilabial fricative [β].

[8][9] The term has been used as a pejorative self-identifier among members of manosphere communities, particularly incels, who do not believe they are assertive or traditionally masculine, and feel overlooked by women.

In some high-quality typesetting, especially in the French tradition, a typographic variant of the lowercase letter without a descender is used within a word for ancient Greek: βίβλος is printed βίϐλος.

[13] In typesetting technical literature, it is a commonly made mistake to use the German letter ß (a s–z or s–s ligature) as a replacement for β.

[14] "Beta" can be used to refer to several consumer and professional videotape formats developed by Japan's Sony Corporation.
