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.

The C1 Controls and Latin-1 Supplement block has been included in its present form, with the same character repertoire since version 1.0 of the Unicode Standard.[3] Its block name in Unicode 1.0 was simply Latin1.[4]

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 .

Latin-1 punctuation and symbols

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.

Mathematical operator
