Tag Latin Small Letter S is a special tag character from the Unicode Tags block, with code point U+E0073. It is not a normal visible letter and is primarily used inside emoji tag sequences, where it represents the lowercase "s" in a hidden tag string. In emoji systems, these tag letters are appended to a base emoji—most notably U+1F3F4 (waving black flag)—and then terminated with the CANCEL TAG character (U+E007F) to request specific subdivision flags like England, Scotland, or Wales. The character does not typically display by itself and is default-ignorable, meaning it should be invisible in most text rendering.
When combined as part of sequences such as 1F3F4 + tag letters + E007F, this character helps spell subtags like "gbsct" (Scotland) or "gbwls" (Wales). On platforms that support these sequences, including Apple/iOS, the result is a single rendered flag for the recognized subdivision; the tag letters, including U+E0073, remain invisible. If the sequence is not recognized, the common fallback is a plain black flag, with all tag characters—including this one—remaining hidden. The Tags block was historically associated with language-tagging concepts and later repurposed for emoji tag sequences, so these characters act more like control/format components than standalone symbols.
