Wikipedia ma następujące informacje na temat tej współrzędnej kodowej:

Wykrzyknik, znak wykrzyknienia – jeden ze znaków pisarskich, składający się z pionowej kreski zakończonej kropką, zwykle u dołu (!), rzadziej u góry (¡). Najczęściej używany jest jako znak interpunkcyjny wyrażający emocje, ale ma także inne zastosowania.

Typograficznie jest znakiem wysokości stopnia pisma, a jego kropka jest dokładnie takiej samej wielkości, kształtu i położenia (o ile znajduje się pod pionową kreską), co znak kropki w tym samym kroju.
