Line 7:
Unicode blocks are identified by unique names, which use only ASCII characters and are usually descriptive of the nature of the symbols, in [[English language|English]]; such as "Tibetan" or "Supplemental Arrows-A". (When comparing block names, one is supposed to equate uppercase with lowercase letters, and ignore any whitespace, hyphens, and underbars; so the last name is equivalent to "supplemental_arrows__a" and "SUPPLEMENTALARROWSA".<ref name=uniblocks>{{Cite web|url=https://www.unicode.org/Public/UNIDATA/Blocks.txt|title=Unicode Blocks data file, Unicode version 15.1|publisher=Unicode Consortium|access-date=2023-09-12}}</ref>
Blocks are [[intersection (set theory)|pairwise disjoint]]; that is, they do not overlap. The starting code point and the size (number of code points) of each block are always multiples of 16; therefore, in the [[hexadecimal notation]], the starting (smallest) point is U+''xxx''0 and the ending (largest) point is U+''yyy''F, where ''xxx'' and ''yyy'' are three or more hexadecimal digits. (These constraints are intended to simplify the display of glyphs in Unicode Consortium documents, as tables with 16
Every assigned code point has a glyph property called "Block", whose value is a character string naming the unique block that owns that point.<ref>{{Cite web |title=Glossary |url=https://www.unicode.org/glossary/#B |access-date=2022-08-07 |website=www.unicode.org}}</ref> However, a block may also contain unassigned code points, usually reserved for future additions of characters that "logically" should belong to that block. Code points not belonging to any of the named blocks, e.g. in the unassigned [[Plane (Unicode)|planes]] 4–13, have the value block="No_Block".<ref name=uniblocks/>
