Hi guys,
I am having a problem with putting French text on one of my php file for my Wordpress site. The special texts appears to be a special character. If the text is on a normal html file it looks okay!

For example, the text should be:
Avantage : Bénéficiez d’un tarif exclusif de 12.38 €/ heure et

But when uploaded it appears like this:
Avantage : B�n�ficiez d�un tarif exclusif de 12.38 €/ heure


Please help!
