Change icons on profile

Hello, I have a problem to change the icons of the profile page.
I followed your tutorials on the subject with Fontello but it does not work for me.

I have added the additional CSS code by modifying the Fontello codes , but these are always the basic icons that appear.

Here is the CSS code I used:

#buddypress div # item-nav UL #messages-Personal-li A:before {content:  “F0E0”;}

#buddypress div # item-nav UL #groups-Personal-li A:before {content:  “E800”;}

#buddypress div # item-nav UL #xprofile-Personal-li A:before {content:  “F2BE”;}

#buddypress div # item-nav UL #activity-Personal-li A:before {content:  “F0AE”;}

#buddypress div # item-nav UL #settings-Personal-li A:before {content:  “E801”;}

#buddypress div # item-nav UL #notifications-Personal-li A:before {content:  “F192”;}

I also tried to put a code Fontello erroneous to see if it changed anything, but nothing either.

Thanks in advance for your help
