punycode_encode - API function
int punycode_encode(size_t input_length, const punycode_uint  input,
const unsigned char  case_flags, size_t * output_length, char  out‐
The number of code points in the input array and the number
of flags in the case_flags array.
const punycode_uint  input
An array of code points. They are presumed to be Unicode
code points, but that is not strictly REQUIRED. The array
contains code points, not code units. UTF-16 uses code
units D800 through DFFF to refer to code points
10000..10FFFF. The code points D800..DFFF do not occur in
any valid Unicode string. The code points that can occur
in Unicode strings (0..D7FF and E000..10FFFF) are also
called Unicode scalar values.
const unsigned char  case_flags
A NULL pointer or an array of boolean values parallel to
the input array. Nonzero (true, flagged) suggests that the
corresponding Unicode character be forced to uppercase
after being decoded (if possible), and zero (false,
unflagged) suggests that it be forced to lowercase (if pos‐
sible). ASCII code points (0..7F) are encoded literally,
except that ASCII letters are forced to uppercase or lower‐
case according to the corresponding case flags. If
case_flags is a NULL pointer then ASCII letters are left as
they are, and other code points are treated as unflagged.
size_t * output_length
The caller passes in the maximum number of ASCII code
points that it can receive. On successful return it will
contain the number of ASCII code points actually output.
char  output
An array of ASCII code points. It is *not* null-termi‐
nated; it will contain zeros if and only if the input con‐
tains zeros. (Of course the caller can leave room for a
terminator and add one if needed.)
Converts a sequence of code points (presumed to be Unicode code points)
The return value can be any of the Punycode_status values defined above
except PUNYCODE_BAD_INPUT. If not PUNYCODE_SUCCESS, then output_size
and output might contain garbage.
