Number Forms is a Unicode block containing Unicode compatibility characters that have specific meaning as numbers, but are constructed from other characters. They consist primarily of vulgar fractions and Roman numerals. In addition to the characters in the Number Forms block, three fractions were inherited from ISO-8859-1, which was incorporated whole as the Latin-1 Supplement block.
In the Unicode standard, a plane is a contiguous group of 65,536 (216) code points. There are 17 planes, identified by the numbers 0 to 16, which corresponds with the possible values 00–1016 of the first two positions in six position hexadecimal format (U+hhhhhh). Plane 0 is the Basic Multilingual Plane (BMP), which contains most commonly used characters. The higher planes 1 through 16 are called "supplementary planes". The last code point in Unicode is the last code point in plane 16, U+10FFFF. As of Unicode version 15.1, five of the planes have assigned code points (characters), and seven are named.
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.

Greek and Coptic is the Unicode block for representing modern (monotonic) Greek. It was originally also used for writing Coptic, using the similar Greek letters in addition to the uniquely Coptic additions. Beginning with version 4.1 of the Unicode Standard, a separate Coptic block has been included in Unicode, allowing for mixed Greek/Coptic text that is stylistically contrastive, as is convention in scholarly works. Writing polytonic Greek requires the use of combining characters or the precomposed vowel + tone characters in the Greek Extended character block.

Tagalog is a Unicode block containing characters of the Baybayin script, specifically the variety used for writing the Tagalog language before and during Spanish colonization of the Philippines eventually led to the adoption of the Latin alphabet. It has been a part of the Unicode Standard since version 3.2 in April 2002. Tagalog characters can be found in the Noto Sans Tagalog font, among others. The Tagalog Baybayin script was originally proposed for inclusion in Unicode alongside its descendant Hanunoo, Buhid and Tagbanwa scripts as a single block called "Philippine Scripts" and two punctuation marks are only part of the Hanunoo block. In 2021, with version 14.0, the Unicode Standard was updated to add three new characters: the "ra" and archaic "ra", and the pamudpod.
