UFB00

U+FB00 LATIN SMALL LIGATURE FF is a Unicode code point in the Alphabetic Presentation Forms block. It encodes the typographic ligature ff used in certain Latin-script texts. The code point is typically written as U+FB00 and exists as a compatibility character to preserve legacy typography in digital text.

In Unicode normalization, U+FB00 is treated as a compatibility form and can be mapped to the two-letter sequence "ff" (U+0066 U+0066) under normalization forms such as NFKC. For modern text processing, it is common to represent the ligature with the two regular letters and rely on font ligatures for typographic rendering.

Rendering and usage: Whether the U+FB00 glyph appears depends on the font and text renderer. Some fonts include a precomposed glyph for U+FB00, while many systems render the ligature by applying font features (the liga feature) to the sequence U+0066 U+0066. In practice, U+FB00 is largely of historical and compatibility interest; contemporary workflows typically avoid relying on it for text representation and instead use the two 'f' characters with ligature support.

Related code points in the same block include U+FB01 LATIN SMALL LIGATURE FI, U+FB02 LATIN SMALL LIGATURE FL, U+FB03 LATIN SMALL LIGATURE FFI, U+FB04 LATIN SMALL LIGATURE FFL, and U+FB05/U+FB06 as other common ligatures. The block as a whole is primarily intended for compatibility with older encodings rather than as a standard method of representing ligatures in new text.
