s      If no l modifier is present: The const char * argument is expected to be a pointer to an array of character type (pointer to a string).   Characters
       from  the array are written up to (but not including) a terminating null byte (’\0’); if a precision is specified, no more than the number specified
       are written.  If a precision is given, no null byte need be present; if the precision is not specified, or is greater than the size  of  the  array,
       the array must contain a terminating null byte.
 
       If  an  l  modifier  is  present: The const wchar_t * argument is expected to be a pointer to an array of wide characters.  Wide characters from the
       array are converted to multibyte characters (each by a call to the wcrtomb() function, with a conversion state starting in the initial state  before
       the  first  wide  character),  up  to and including a terminating null wide character. The resulting multibyte characters are written up to (but not
       including) the terminating null byte. If a precision is specified, no more bytes than the number specified are written,  but  no  partial  multibyte
       characters  are written. Note that the precision determines the number of bytes written, not the number of wide characters or screen positions.  The
       array must contain a terminating null wide character, unless a precision is given and it is so small that the number of  bytes  written  exceeds  it
