Combining Half Marks is a Unicode block containing diacritic mark parts for spanning multiple characters.
A Unicode block is one of several contiguous ranges of numeric character codes of the Unicode character set that are defined by the Unicode Consortium for administrative and documentation purposes. Typically, proposals such as the addition of new glyphs are discussed and evaluated by considering the relevant block or blocks as a whole.

Combining Diacritical Marks is a Unicode block containing the most common combining characters. It also contains the character "Combining Grapheme Joiner", which prevents canonical reordering of combining characters, and despite the name, actually separates characters that would otherwise be considered a single grapheme in a given context.
In digital typography, combining characters are characters that are intended to modify other characters. The most common combining characters in the Latin script are the combining diacritical marks.
As of Unicode version 12.0 Cyrillic script is encoded across several blocks, all in the BMP:
Combining Diacritical Marks Supplement is a Unicode block containing combining characters for the Uralic Phonetic Alphabet, Medievalist notations, and German dialectology (Teuthonista). It is an extension of the diacritic characters found in the Combining Diacritical Marks block.
Spacing Modifier Letters is a Unicode block containing characters for the IPA, UPA, and other phonetic transcriptions. Included are the IPA tone marks, and modifiers for aspiration and palatalization.
Combining Diacritical Marks for Symbols is a Unicode block containing arrows, dots, enclosures, and overlays for modifying symbol characters.
Supplemental Punctuation is a Unicode block containing historic and specialized punctuation characters, including biblical editorial symbols, ancient Greek punctuation, and German dictionary marks.
Yi Syllables is a Unicode block containing the characters of the Liangshan Standard Yi script for writing the Nuosu, or Yi, language.
Specials is a short Unicode block allocated at the very end of the Basic Multilingual Plane, at U+FFF0–FFFF. Of these 16 code points, five are assigned as of Unicode 12.0:
Cyrillic Extended-B is a Unicode block containing Cyrillic characters for writing Old Cyrillic and Old Abkhazian, and combining numeric signs.
IPA Extensions is a block (0250–02AF) of the Unicode standard that contains full size letters used in the International Phonetic Alphabet (IPA). Both modern and historical characters are included, as well as former and proposed IPA signs and non-IPA phonetic letters. Additional characters employed for phonetics, like the palatalization sign, are encoded in the blocks Phonetic Extensions (1D00–1D7F) and Phonetic Extensions Supplement (1D80–1DBF). Diacritics are found in the Spacing Modifier Letters (02B0–02FF) and Combining Diacritical Marks (0300–036F) blocks.
Latin Extended Additional is a Unicode block.
CJK Symbols and Punctuation is a Unicode block containing symbols and punctuation used for writing the Chinese, Japanese and Korean languages.
Greek and Coptic is the Unicode block for representing modern (monotonic) Greek. It was originally 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.
Greek Extended is a Unicode block containing the accented vowels necessary for writing polytonic Greek. The regular, unaccented Greek characters as well as the characters with tonos and diaeresis can be found in the Greek and Coptic. Greek Extended was encoded in version 1.1 of the Unicode Standard. As an alternative to Greek Extended, combining characters can be used to represent the tones and breath marks of polytonic Greek.
Ethiopic Supplement is a Unicode block containing extra Geʽez characters for writing the Sebatbeit language, and Ethiopic tone marks.
Devanagari Extended is a Unicode block containing cantilation marks for writing the Samaveda, and nasalization marks for the Devanagari script.
Egyptian Hieroglyphs is a Unicode block containing the Gardiner's sign list of Egyptian hieroglyphs.
Javanese is a Unicode block containing aksara Jawa characters traditionally used for writing the Javanese language. The Javanese script was added to the Unicode Standard in October 2009 with the release of version 5.2.
Halfwidth and Fullwidth Forms is the name of a Unicode block U+FF00–FFEF, provided so that older encodings containing both halfwidth and fullwidth characters can have lossless translation to/from Unicode. It is the last of the Basic Multilingual Plane excepting the short Specials block at U+FFF0–FFFF.
Combining Diacritical Marks Extended is a Unicode block containing diacritical marks used in German dialectology (Teuthonista).
