U+E0022 "󠀢" Tag Quotation Mark Unicode Character

It is not intended for normal visible quotation or punctuation use, and its function is primarily to act as a closing tag in a sequence of invisible tag characters, following the mechanism of Unicode's language tagging system. This character is rarely encountered in everyday text and is mostly relevant for historical or specialized digital data interchange contexts.
