NAME

       tickit_utf8_put - append a UTF-8 encoded codepoint to a buffer

SYNOPSIS

       #include <tickit.h>

       size_t tickit_utf8_put(char *str, size_t len, long codepoint);

       Link with -ltickit.

DESCRIPTION

       tickit_utf8_put()  appends bytes into a buffer to represent the given codepoint. The UTF-8
       bytes will be appended directly starting from str, and the function then returns the total
       number  of  bytes  appended.  The  length  of the buffer should be given to as len; if the
       buffer is not long enough then it is left unmodified and -1 is returned instead. If str is
       NULL  then  the function will simply return the number of bytes it would need to append to
       represent the codepoint.

       This function does not expect the buffer to be NUL-terminated, and it will  not  terminate
       the buffer with a NUL byte on completion.

RETURN VALUE

       tickit_utf8_put()  returns the number of bytes appended to the buffer, or -1 if the buffer
       was not long enough.
