-    punycode_encode() converts a sequence of code points (presumed to be
-    Unicode code points) to Punycode.
-
-    Input arguments (to be supplied by the caller):
-
-        input_length
-            The number of code points in the input array and the number
-            of flags in the case_flags array.
-
-        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.
-
-        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 possible).
-            ASCII code points (0..7F) are encoded literally, except that
-            ASCII letters are forced to uppercase or lowercase 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.
-
-    Output arguments (to be filled in by the function):
-
-        output
-            An array of ASCII code points.  It is *not* null-terminated;
-            it will contain zeros if and only if the input contains
-            zeros.  (Of course the caller can leave room for a
-            terminator and add one if needed.)
-
-    Input/output arguments (to be supplied by the caller and overwritten
-    by the function):
-
-        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.
-
-    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.

-            would be harmless.

-            the maximum number of flags that it can receive into the
-            case_flags array, if case_flags is not a null pointer).  On
-            successful return it will contain the number of code points
-            actually output (which is also the number of flags actually
-            output, if case_flags is not a null pointer).  The decoder
-            will never need to output more code points than the number
-            of ASCII code points in the input, because of the way the
-            encoding is defined.  The number of code points output
-            cannot exceed the maximum possible value of a punycode_uint,
-            even if the supplied output_length is greater than that.
-
-    Return value:
-
-        Can be any of the punycode_status values defined above.  If not
-        punycode_success, then output_length, output, and case_flags
-        might contain garbage.
