Functions
std::string	Ase::utf8encode (const std::vector< uint32_t > &codepoints)
	Convert codepoints into an UTF-8 string, using the shortest possible encoding.
std::string	Ase::utf8encode (const uint32_t *codepoints, size_t n_codepoints)
	Convert codepoints into an UTF-8 string, using the shortest possible encoding.
String	Ase::string_to_ncname (const String &input, uint32_t substitute)
	Convert input to a NCName, according to the QName EBNF.
bool	Ase::string_is_ncname (const String &input)
	Check input to be a NCName, according to the QName EBNF.
size_t	Ase::utf8_to_unicode (const std::string &str, std::vector< uint32_t > &codepoints)
	Convert valid UTF-8 sequences to Unicode codepoints, invalid sequences are treated as Latin-1 characters.
size_t	Ase::utf8_to_unicode (const char *str, uint32_t *codepoints)
	Convert valid UTF-8 sequences to Unicode codepoints, invalid sequences are treated as Latin-1 characters.
size_t	Ase::utf8len (const std::string &str)
	Count valid UTF-8 sequences, invalid sequences are counted as Latin-1 characters.
size_t	Ase::utf8len (const char *str)
	Count valid UTF-8 sequences, invalid sequences are counted as Latin-1 characters.
constexpr bool	Ase::unicode_is_valid (uint32_t u)
	Return whether u is an allowed Unicode codepoint within 0x10FFFF and not part of a UTF-16 surrogate pair.
constexpr bool	Ase::unicode_is_assigned (uint32_t u)
	Return whether u matches any of the assigned Unicode planes.
constexpr bool	Ase::unicode_is_noncharacter (uint32_t u)
	Return whether u is one of the 66 Unicode noncharacters.
constexpr bool	Ase::unicode_is_character (uint32_t u)
	Return whether u is not one of the 66 Unicode noncharacters.
constexpr bool	Ase::unicode_is_control_code (uint32_t u)
	Return whether u is one of the 65 Unicode control codes.
constexpr bool	Ase::unicode_is_private (uint32_t u)
	Return whether u is in one of the 3 private use areas of Unicode.
std::string	Ase::encodefs (const std::string &fschars)
	Encode a file system path consisting of bytes into UTF-8, using surrogate code points to store non UTF-8 bytes.
std::string	Ase::decodefs (const std::string &utf8str)
	Decode UTF-8 string back into file system path representation, extracting surrogate code points as bytes.
std::string	Ase::displayfs (const std::string &utf8str)
	Convert UTF-8 encoded file system path into human readable display format, the conversion is lossy but readable.
std::vector< uint32_t >	Ase::utf8decode (const std::string &utf8str)
	Convert valid UTF-8 sequences to Unicode codepoints, invalid sequences are treated as Latin-1 characters.
