Circumflex
How Circumflex works
The circumflex (^) as a diacritical mark sits above vowels in French (hotel, etre, foret) where it often signals a dropped historical "s" - compare French "foret" with English "forest." Portuguese, Romanian, and Vietnamese also use circumflex vowels.
In ASCII, code 94 is the caret (^), which looks like a circumflex but serves a different purpose in programming - bitwise XOR in C, exponentiation in some languages, and escape prefix in terminal control sequences. Pre-composed circumflex letters like o and e are not in ASCII but appear in ISO-8859-1. See the full set in our circumflex character group or find the HTML entities for web use.
