@subheading pr29_8z @anchor{pr29_8z} @deftypefun {int} {pr29_8z} (const char * @var{in}) @var{in}: zero terminated input UTF-8 string. Check the input to see if it may be normalized into different strings by different NFKC implementations, due to an anomaly in the NFKC specifications. Return value: Returns the @code{Pr29_rc} value @code{PR29_SUCCESS} on success, and @code{PR29_PROBLEM} if the input sequence is a "problem sequence" (i.e., may be normalized into different strings by different implementations), or @code{PR29_STRINGPREP_ERROR} if there was a problem converting the string from UTF-8 to UCS-4. @end deftypefun
