       punycode_encode - API function

       #include <punycode.h>

       int  punycode_encode(size_t input_length, const punycode_uint [] input,
       const unsigned char [] case_flags, size_t * output_length, char [] out‐

       size_t input_length
		   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)
       to Punycode.

       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.
