All input strings (both UTF-8 and UTF-32) are considered +to be NUL-terminated when use as input. Output strings are always NUL terminated +unless specified otherwise. +.Pp +Functions prefixed with +.Dq uni8_ +are referring to UTF-8 source or destination. +.Pp +Functions prefixed with +.Dq uni32_ +are analogous to their respective +.Dq uni8_ +counterparts if applicable. +.Pp +Finally, generic functions prefixed with +.Dq uni_ +do not perform any conversion and are made for character class classificiation. +.Pp +The +.Fn uni8_encode +function transforms the unicode character +.Fa point +and store the result as UTF-8 string into +.Fa dst +of +.Fa dstsz +bytes long. The output string is +.Em not +NUL terminated and must be at least 4 bytes long, otherwise it may be truncated. +.Pp +The +.Fn uni8_decode +function reads the UTF-8 NUL-terminated +.Fa src +input string and converts the result into +.Fa point +as unicode character. +.Pp +The +.Fn uni8_sizeof +function returns the number of bytes that are following the byte +.Fa c +in a multibytes sequence. It can be used while iterating a UTF-8 string to jump +a specific number of bytes while encountering a multibytes sequence. +.Pp +The +.Fn uni8_length +function returns the number of unicode characters (which is lesser or equal of +the number of bytes) in the UTF-8 NUL terminated +.Fa src +string. +.Pp +The +.Fn uni8_to32 +function converts the UTF-8 +.Fa src +input string into the +.Fa dst +array of +.Fa dstsz +bytes long. The function writes at most +.Fa dstsz +bytes including the NUL terminator character, make sure to reserve an additional +space for it before calling this function. +.Pp +The +.Fn uni32_sizeof +function returns the number of UTF-8 characters required to convert the unicode +.Fa point +character to UTF-8. +.Pp +The +.Fn uni32_length +function returns the number of unicode characters present in the UTF-32 NUL +terminated +.Fa src +string. +.Pp +The +.Fn uni32_requires +function computes the total number of bytes (excluding the NUL terminator) that +are required to build a UTF-8 string from the UTF-32 NUL terminated +.Fa src +string. +.Pp +The +.Fn uni32_to8 +function converts the UTF-32 NUL terminated +.Fa src +string and stores the result as UTF-8 in +.Fa dst +of +.Fa dstsz +bytes long. The function writes at most +.Fa dstsz +bytes including the NUL terminator character, make sure to reserve an additional +space for it before calling this function. +.Pp +The +.Fn uni_isalpha +returns non-zero if the the unicode character +.Fa point +is considered alphanumeric class. +.Pp +The +.Fn uni_isdigit +returns non-zero if the the unicode character +.Fa point +is considered numeric class. +.Pp +The +.Fn uni_islower +returns non-zero if the the unicode character +.Fa point +is considered lower case class. +.Pp +The +.Fn uni_istitle +returns non-zero if the the unicode character +.Fa point +is considered title case class. +.Pp +The +.Fn uni_isupper +returns non-zero if the the unicode character +.Fa point +is considered upper case class. +.Pp +The +.Fn uni_toupper +returns the upper case variant of the unicode character +.Fa point . +.Pp +The +.Fn uni_tolower +returns the lower case variant of the unicode character +.Fa point . +.Pp +The +.Fn uni_totitle +returns the title case variant of the unicode character +.Fa point . +.\" RETURN VALUES +.Sh RETURN VALUES +The +.Fn uni8_encode , +.Fn uni8_to32 +and +.Fn uni32_to8 +functions return the number of bytes written (excluding NUL terminator) into +.Fa dst +or -1 in case of error. +.Pp +The +.Fn uni8_decode +function returns the number of bytes parsed from +.Fa src +string or -1 in case of error. +.Pp +The +.Fn uni8_sizeof +and +.Fn uni8_length +functions return -1 in case of error. +.Pp +The +.Fn uni32_sizeof +and +.Fn uni32_requires +functions return -1 in case of error. +.\" ERRORS +.Sh ERRORS +The global +.Va errno +variable can be set in case of error using the following macro constants: +.Bl -tag -width Er +.It Bq Er EILSEQ +When an invalid sequence was found.
