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). Controls C1 (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. Its block name in Unicode 1.0 was simply Latin1.

2. 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).[1]

2.1. 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.[1]

2.2. 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.[1]

2.3. 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 not commonly used word-initially.[1]

2.4. Mathematical Operator

The Mathematical operator subheading is used for the multiplication and division signs.[1]

3. Number of Symbols, Letters and Control Codes

The table below shows the number of each letters, symbols and control codes in each subheadings in the C1 Controls and Latin-1 Supplement block.

Type of subheading Number of symbols Range of characters
C1 controls 32 control codes U+0080 to U+009F
Latin-1 punctuation and symbols 32 punctuation and symbols U+00A0 to U+00BF
Letters 30 pairs of majuscule and minuscule accented Latin characters U+00C0 to U+00D6, U+00D8 to U+00F6 and U+00F8 to U+00FF
Mathematical operators The U+00D7 × MULTIPLICATION SIGN and U+00F7 ÷ DIVISION SIGN symbols. U+00D7 and U+00F7

4. Emoji

The Latin-1 Supplement block contains two emoji: U+00A9 and U+00AE.[2][3]

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.[4]
