#include <fontconfig.h> FcBool FcUtf16Len(FcChar8 *src); (FcEndian endian); (int len); (int *nchar); (int *wchar); .fi
Counts the number of Unicode chars in len bytes of src. Bytes of src are combined into 16-bit units according to endian. Places that count in nchar. wchar contains 1, 2 or 4 depending on the number of bytes needed to hold the largest unicode char counted. The return value indicates whether string is a well-formed UTF16 string.
