No, we accept any language. Geni's unicode accepts all international characters, so you would enter the accent the same way you would in Word or any other application.
Also, you may use the 'Account' dropdown in the upper right-hand corner of your Geni account and the "Change Language" option to switch your language from English to another one of your choice. You will be able to switch back to English at anytime.
