The Wikipedia has the following information about this codepoint:
よ, in hiragana or ヨ in katakana, is one of the Japanese kana, each of which represents one mora. The hiragana is made in two strokes, while the katakana in three. Both represent [jo].
When small and preceded by an -i kana, this kana represents a palatalization of the preceding consonant sound with the [o] vowel (see yōon).
In mathematics, よ is sometimes used to represent the Yoneda embedding.
