U+E0028 "󠀨" Tag Left Parenthesis Unicode Character

Unicode Version 17.0

󠀨

U+E0028 "󠀨" Tag Left Parenthesis is a special invisible character belonging to the Tags block, designed for use in plain text to encode invisible metadata or language tags without affecting visible formatting. It represents an opening parenthesis within the Unicode tag mechanism, where a sequence of tag characters starting with U+E0001 Language Tag and ending with U+E007F Cancel Tag can mark specific language or script information for text processing applications. As a deprecated feature in favor of newer marker methods, this character is seldom used outside specialized systems and appears as a control code rather than a visible glyph in most environments.
