[:blank:] is series of characters for that:
(string-match "[[:blank:]]" " ") ⇒ 0
Match new lines as blanks:
(string-match "[[:blank:]]" "
") ⇒ 0
There can be many various spaces, like EM SPACE: " "
Thus this will not work on EM SPACE:
(string-match " +" " ") ⇒ nil
But this will work:
(string-match "[[:blank:]]" " ") ⇒ 0
