Its character set is continued in the following Unicode block, Phonetic Extensions Supplement.
The 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.
Cyrillic Extended-A is a Unicode block containing Cyrillic combining characters used in Old Church Slavonic texts.

Enclosed Alphanumeric Supplement is a Unicode block consisting of Latin alphabet characters and Arabic numerals enclosed in circles, ovals or boxes, used for a variety of purposes. It is encoded in the range U+1F100–U+1F1FF in the Supplementary Multilingual Plane.
Cyrillic is a Unicode block containing the characters used to write the most widely used languages with a Cyrillic orthography. The core of the block is based on the ISO 8859-5 standard, with additions for minority languages and historic orthographies.
Georgian Supplement is a Unicode block containing characters for the ecclesiastical form of the Georgian script, Nuskhuri. To write the full ecclesiastical Khutsuri orthography, the Asomtavruli capitals encoded in the Georgian block.
Cherokee is a Unicode block containing the syllabic characters for writing the Cherokee language. When Cherokee was first added to Unicode in version 3.0 it was treated as a unicameral alphabet, but in version 8.0 it was redefined as a bicameral script. The Cherokee block contains all the uppercase letters plus six lowercase letters. The Cherokee Supplement block, added in version 8.0, contains the rest of the lowercase letters. For backwards compatibility, the Unicode case folding algorithm—which usually converts a string to lowercase characters—maps Cherokee characters to uppercase.
Hiragana is a Unicode block containing hiragana characters for the Japanese language.
Katakana is a Unicode block containing katakana characters for the Japanese and Ainu languages.
Variation Selectors Supplement is a Unicode block containing additional variation selectors beyond those found in the Variation Selectors block.

It contains three such characters containing one or more kana, and many containing CJK ideographs. Many of its characters were added for compatibility with the Japanese ARIB STD-B24 standard. Six symbols from Chinese folk religion were added in Unicode version 10.
Cherokee Supplement is a Unicode block containing the syllabic characters for writing the Cherokee language. When Cherokee was first added to Unicode in version 3.0 it was treated as a unicameral alphabet, but in version 8.0 it was redefined as a bicameral script. The Cherokee Supplement block contains lowercase letters only, whereas the Cherokee block contains all the uppercase letters, together with six lowercase letters. For backwards compatibility, the Unicode case folding algorithm—which usually converts a string to lowercase characters—maps Cherokee characters to uppercase.
