Attributes

	Name
const uint32_t[32]	windows1252_to_unicode
constexpr double	ESCAPE_PATTERN_MATCH_BOOST Score boost for dialects matching detected escape patterns (e.g., ” or ““) Applied when there’s a clear escape pattern signal in the data.
constexpr double	DOUBLE_QUOTE_ESCAPE_BOOST Smaller boost for double-quote escaping when explicitly detected Used to slightly prefer RFC 4180 style when evidence is present.
