function
<cwchar>
wctob
Convert wide character to single byte
Returns the single-byte representation of the wide character wc if (and only if) wc corresponds to a multibyte character with a length of a single byte in the initial state of a multibyte sequence.
Otherwise, it returns EOF.
Parameters
- wc
- The wint_t promotion of a wide character.
The value is internally converted to a wchar_t to be interpreted.
Return Value
If wc translates to a single-byte character in the initial shift state of a multibyte sequence, the function returns its representation as an unsigned char (promoted to a value of type int).
Otherwise, it returns EOF.

Output:
wcs contains 14 characters that translate to single-byte characters.
