Test char at point

I want to test if char at point is, let's say, "{"

I found:

(string= "{" (buffer-substring-no-properties (point) (+ 1 (point))))

and:

(string-match-p "{" (what-cursor-position))

both working.

In the sencond case, if there isn't something better, I'd like to hide the message in the echo area (minibuffer).

Some hint?
