Error display specials characters

My SQL Database is an UTF-8.
In ```
\includes\languages\french.php SETLOCALE is : @setlocale(LC_TIME, 'fr', 'french', 'fra', 'fr_FR', 'fr_FR@euro');

and ```
CHARSET is : define('CHARSET', 'utf-8');

When i write a product description, i use ISO Entities as

é 	é 	é   	lowercase e, acute accent

or

à 	à 	à   	lowercase a, grave accent

The specials characters are stored well in my data base, e.g ```
Très grand format donnant des reflets colorés

But when i return into a product description and what i update, in the display the special characters are replaced by a question mark in a black triangle. 

How to correct that?

try doing this its a keystoke.
for the
è do this alt + 0232
for the
à do this alt + 0224

you can find this info by going to your character map on your computer.
