The Wikipedia has the following information about this codepoint:

The exclamation mark, !, or exclamation point (American English), is a punctuation mark usually used after an interjection or exclamation to indicate strong feelings or to show emphasis. The exclamation mark often marks the end of a sentence, for example: "Watch out!". Similarly, a bare exclamation mark (with nothing before or after) is often established in warning signs. The exclamation mark is often used in writing to make a character seem as though they are shouting and/or excited/surprised.

Other uses include:

  • In mathematics, it denotes the factorial operation.
  • Several computer languages use ! at the beginning of an expression to denote logical negation. For example,!A means "the logical negation of A", also called "not A". This usage has spread to ordinary language (e.g. "!clue" means no-clue or clueless).
  • Some languages use ! to denote a click consonant.
