U+E0066 "" Tag Latin Small Letter F Unicode Character
Unicode Version 17.0
U+E0066 "" Tag Latin Small Letter F is a format character belonging to the Tags block, specifically designed for use within language tagging protocols where it combines with other tag characters to represent the ISO 639-1 code for a language, such as the letter 'f' in "en" (English) or "fr" (French). This character is intended for invisible or metadata usage and is not typically displayed as a visible glyph in normal text, instead functioning as a control character that helps software or standards like Unicode’s Language Tags mechanism identify language context in plain text.
