Instance Method Details

#contextual_accent_from_token(value) ⇒ Object

Promotes an accent character to its function class. Callers must only use this from an accent position; elsewhere the character has to stay a plain symbol/text. Decode-then-encode normalizes both call sites: MathML passes an already-encoded "̃", OMML passes the raw U+0303.
