U+E007C "󠁼" Tag Vertical Line Unicode Character

U+E007C "󠁼" Tag Vertical Line is a special purpose character belonging to the Unicode Tags block, specifically designed for use within language tag sequences defined by the Unicode Technical Standard for tagging text with language information. It represents a vertical line glyph used as a formatting component in these invisible tag sequences, which are primarily employed to denote the language of surrounding text without affecting visible rendering. This character itself is not intended for standalone display and typically appears only in contexts where tag processing is supported, such as in some text processing systems or older email standards, and its implementation requires compatible software to interpret the tags correctly.
