Classes
struct	real::detail::decoded_codepoint
	The result of a strict UTF-8 decode: the code point, its byte length, and validity. More...

Namespaces
namespace	real
	REAL's public API: real::regex, real::static_regex, real::flags and the match/iterator types built on them.

namespace	real::detail
	DFA construction internals: subset construction over a flattened NFA. Not a stable API.

Functions
constexpr decoded_codepoint	real::detail::decode_codepoint_strict (std::string_view text, std::size_t pos)
	Strictly decodes and validates the UTF-8 sequence at `text[pos]`.

constexpr std::size_t	real::detail::codepoint_advance (std::string_view text, std::size_t pos)
	Number of bytes from `pos` to the next code-point boundary, for advancing past an empty match during iteration.

constexpr std::size_t	real::detail::codepoint_retreat (std::string_view text, std::size_t end, std::size_t floor)
	Width of the last code point before `end`, the mirror of codepoint_advance.
