U+E0021 "" Tag Exclamation Mark Unicode Character
Unicode Version 17.0
U+E0021 "" Tag Exclamation Mark is a formatting character used exclusively within the Unicode tag mechanism, specifically part of a block of 95 visible ASCII tag characters designed for special text processing. It serves as a visible tag glyph representing the exclamation mark symbol, but unlike standard punctuation, it is not intended for regular text display; instead, it functions as a control character used in combination with other tag characters to modify or label text in ways such as indicating language or providing metadata, though its practical use is extremely limited and it is not supported in most modern software and fonts.
