Block from U+0080 to U+00FF. This block was introduced in Unicode version 1.1 (1993). It contains 128 codepoints.
The Wikipedia provides the following information on block 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). Controls C1 (0080–009F) are not graphic.
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, where it was known as Latin 1.
