wcswidth − determine columns needed for a fixed-size wide character string
#include <wchar.h>
int wcswidth (const wchar_t *s, size_t n);
The wcswidth function returns the number of columns needed to represent the wide-character string pointed to by s, but at most n wide characters. If a non-printable wide character occurs among these characters, -1 is returned.
The wcswidth function returns the number of column positions for the wide-character string s, truncated to at most length n.
