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
namespace	real::detail

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.

Detailed Description

UTF-8 position arithmetic for match iteration.

The matching engine never needs this — multi-byte constructs are compiled to byte-level alternatives. It is used only by match iteration to advance past an empty match by one whole codepoint, matching Python's behaviour.
