Capital AA with caret, showing on all buttons

Situation
All buttons are showing 2 capital As, with carets - ÂÂ
inspecting the html, it is in before content:
.btn-show::before {
content: "\f06e  ";
}
I suspect I have the wrong encoding, I set mySQL to utf8_general_ci ?
If thats it, what should I be using pls?
