Latin-1 Supplement

The Latin-1 Supplement (also called C1 Controls and Latin-1 Supplement) is the second Unicode block in the Unicode standard. It encodes the upper range of ISO 8859-1: 80 (U+0080) - FF (U+00FF). C1 Controls (0080–009F) are not graphic. This block ranges from U+0080 to U+00FF, contains 128 characters and includes the C1 controls, Latin-1 punctuation and symbols, 30 pairs of majuscule and minuscule accented Latin characters and 2 mathematical operators.

Not to be confused with ISO/IEC 8859-1.
For a list of all Latin characters encoded in Unicode, see Latin script in Unicode.

Subheadings

The C1 Controls and Latin-1 Supplement block has four subheadings within its character collection: C1 controls, Latin-1 Punctuation and Symbols, Letters, and Mathematical operator(s).[5]

C1 controls

The C1 controls subheading contains 32 supplementary control codes inherited from ISO/IEC 8859-1 and many other 8-bit character standards. The alias names for the C0 and C1 control codes are taken from ISO/IEC 6429:1992.[5]

Latin-1 punctuation and symbols

The Latin-1 Punctuation and Symbols subheading contains 32 characters of common international punctuation characters, such as inverted exclamation and question marks, and a middle dot; and symbols like currency signs, spacing diacritic marks, vulgar fraction, and superscript numbers.[5]

Letters

The Letters subheading contains 30 pairs of majuscule and minuscule accented or novel Latin characters for western European languages, and two extra minuscule characters (ß and ÿ) not commonly used as the first letter of words.[5]

Mathematical operator

The Mathematical operator subheading is used for the multiplication and division signs.[5]

Emoji

The Latin-1 Supplement block contains two emoji: U+00A9 and U+00AE.[6][7]

The block has four standardized variants defined to specify emoji-style (U+FE0F VS16) or text presentation (U+FE0E VS15) for the two emoji, both of which default to a text presentation.[8]
