24/// The version of [Unicode](https://www.unicode.org/) that the Unicode parts of
25/// `char` and `str` methods are based on.
26///
27/// New versions of Unicode are released regularly and subsequently all methods
28/// in the standard library depending on Unicode are updated. Therefore the
29/// behavior of some `char` and `str` methods and the value of this constant
30/// changes over time. This is *not* considered to be a breaking change.
31///
32/// The version numbering scheme is explained in
33/// [Unicode 11.0 or later, Section 3.1 Versions of the Unicode Standard](https://www.unicode.org/versions/Unicode11.0.0/ch03.pdf#page=4).
