Tag Latin Small Letter B (U+E0062) is a Unicode tag character from the Tags block used to build emoji tag sequences, not a standalone emoji. It is a default-ignorable, invisible format character that normally does not display by itself and should not be used as ordinary text. Its primary role in emoji systems is to encode specific tag strings when appended to a base emoji, contributing one lowercase βbβ to that sequence. If rendered outside a valid tag sequence, it is typically ignored; in some environments without proper handling, it may appear as a missing-glyph box.
In emoji construction, tag letters follow a base such as U+1F3F4 BLACK FLAG and are terminated by U+E007F CANCEL TAG. The most prominent use is forming subdivision flags for parts of the United Kingdom, where the tag string represents a BCP 47-like subtag. For example, the sequence for the England flag uses BLACK FLAG plus the tag letters for βgbeng,β where this character supplies the βbβ; Scotland uses βgbsct,β and Wales uses βgbwls.β Only certain curated tag sequences are recognized for emoji presentation across platforms.
On Apple/iOS, this character is invisible by itself and functions only as part of supported emoji tag sequences; recognized sequences render as the intended flag (e.g., England, Scotland, Wales), while unsupported ones typically fall back to a plain black flag or are ignored. Developers should include the CANCEL TAG terminator and be aware that default-ignorable characters may be stripped by normalization, sanitization, or text processing pipelines. This tag letter is a technical component for emoji composition and has cultural visibility only when it helps form a fully supported flag emoji in a larger sequence.
