UTF-8 / filesystem path conversion utilities.

Provides cross-platform helpers for converting between UTF-8 encoded std::string values and std::filesystem::path objects. On Windows, two additional helpers convert between UTF-8 std::string and std::wstring using the Win32 MultiByteToWideChar / WideCharToMultiByte APIs.

Functions

inline std::filesystem::path utf8_to_path(const std::string &utf8)

Converts a UTF-8 encoded string to a std::filesystem::path.

On Windows the string is first widened via utf8str_to_wstring so that non-ASCII characters in the path are handled correctly. On all other platforms the path is constructed directly from the UTF-8 string.

Parameters:

utf8 – UTF-8 encoded path string.

Returns:

Corresponding std::filesystem::path.

inline std::string path_to_utf8(const std::filesystem::path &p)

Converts a std::filesystem::path to a UTF-8 encoded string.

On Windows the path’s native wide string is converted to UTF-8 via wstring_to_utf8str. On all other platforms the path’s native string representation (already UTF-8) is returned directly.

Parameters:

p – Filesystem path to convert.

Returns:

UTF-8 encoded string representation of p.
