E.4 R3 Pattern_White_Space and Pattern_Syntax characters[uaxid.pattern]
1 <https://eel.is/c++draft/uaxid.pattern#1>
UAX #31 describes how languages that use or interpret patterns of
characters, such as regular expressions or number formats, may describe
that syntax with Unicode properties.
2 <https://eel.is/c++draft/uaxid.pattern#2>
C++ does not do this as part of the language, deferring to library
components for such usage of patterns.

This requirement does not apply to C++.

*1 <https://eel.is/c++draft/uaxid.pattern#1> *UAX#31 describes how formal
languages such as computer languages should describe and implement their
use of whitespace and syntactically significant characters during the
processes of lexing and parsing. C++ does not claim conformance with this
