Character Manipulation Function
int isblank(int c);
int iswblank(wint_t wc);
Internationalization (I18n) Function Overview
The isblank function returns true if c is a blank character; that is, a space or a tab.
The iswblank function is the wide version of the isblank function and returns true if wc is a blank character.
I18n Issues
There is no UTF-8 version of isblank. Instead, convert the multibyte character to a wide character and
call iswblank.
Prior to calling iswalnum, ensure that the locale is set correctly, since
the result of the test condition depends on the locale's LC_CTYPE category setting.
