U+E004F "󠁏" Tag Latin Capital Letter O Unicode Character

U+E004F "󠁏" Tag Latin Capital Letter O is a special purpose character belonging to the Tags block, which is used exclusively for historical text encoding purposes related to language tagging in plain text, such as in early Unicode normalization or the deprecated ISO 11940 Thai transliteration standard. It represents a formatting character that indicates a tag for the Latin capital letter O, functioning as part of a sequence to mark a language or script tag within a string rather than as a visible glyph. This character, like others in the Tags block, is not intended for normal text display and is typically invisible in modern rendering, serving instead as metadata for legacy systems that required explicit tagging of language or script boundaries.
