ff1b

ff1b is a hexadecimal string that can denote different things depending on context. The most established interpretation in computing is a Unicode code point: U+FF1B. This code point represents the fullwidth semicolon, a punctuation mark used in East Asian typography to accommodate fullwidth characters in text that is otherwise monospaced. The glyph is；. In text encoding, U+FF1B can be written as the Unicode escape sequence \uFF1B, or as an HTML entity ；. It belongs to the Unicode Fullwidth and Halfwidth Forms block, which contains variants intended to align with fullwidth Latin and script characters.

Outside of Unicode, "ff1b" may appear as a hex fragment in various domains without a single universal meaning. For example, in software configuration or data identifiers, it might be part of a tag, a version label, or a filename. Without additional context, the sequence does not imply a specific standard or operation.

In summary, ff1b most reliably refers to the Unicode code point U+FF1B when encountered in text encoding, corresponding to the fullwidth semicolon used in East Asian typography. For other uses, consultation of the specific domain or document where the term appears is required.
