first-letter initial quote doesn't work in firefox

[pil0t]

I quite dont get it here, firefox doesn't want to accept ❝ (U-275D) as my first letter dispite the fact that they are supposed to accept initial quote.Does anybody have any idea ? http://jsfiddle.net/DXn3B/1/\[code\].who{ font-family: 'Open Sans', sans-serif; font-weight:lighter; color:#565656; font-size:1em;}.who:first-letter{ float: left; font-size: 2.5em; line-height: 1; margin-right: 0.2em;}.who:before{ content: '\275d'; color:#272727;}.who:after{ content: '\275e'; color:#272727; font-size: 2.5em; font-family: 'Coverdale-Condensed', sans-serif;}\[/code\]
