== Unicode blocks ==
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 Blocks, Retrieved 2017-11-03.txt] </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>
Every block is an interval of code points. 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 of all Unicode code points. The number of code points in a block varies. Some have just 16 code points, and some others have thousands of code points.
so {{code|context}} is indeed, and as expected, taking some of the glyphs from the fallback font, which, in this case, is provided by the local operating system.
