A Unicode block, or, simply, a block, is any of the subsets of the Unicode code space that are listed in the file {{code|Blocks.txt}}<ref name="Blocks">The Unicode Consortium, ''Blocks.txt'', ftp://www.unicode.org/Public/UNIDATA/Blocks.txt, Retrieved 2017-11-03.</ref> of the Unicode Character Database. The Unicode code space is the set of all code points, that is, the set of all integers from 0 to the integer whose hexadecimal representation is 10FFF.
The main properties of blocks are described in D10b of Section 3.4 of the Unicode standard<ref>The Unicode Consortium, ''The Unicode Standard'', Version 10.0.0, The Unicode Consortium, Mountain View, CA, USA, 2016, http://www.unicode.org/versions/Unicode10.0.0/UnicodeStandard-10.0.pdf, Retrieved 2017-11-03.</ref> (Section 3.4, paragraph D10b). Every block is an interval of code points. Different , and different blocks are disjoint from each other, and every code point belongs to at least one block. Thus, the blocks form a partition of the set a subset of all Unicode code pointsspace. The number of code points in a block varies. Some have just 16 code points, and some others have thousands of code points.Every code point
A code block starts at a code point that is a multiple of 16. The number of code points in each block is also a multiple of 16. Thus, the hexadecimal representation of the first code point in a block is of the form ''pqrs''0, and that of the last code point in it is of the form ''tuvw''F, where ''p'', ''q'', ''r'', ''s'', ''t'', ''u'', ''v'', and ''w'', are hexadecimal digits.
