On several fields in the theme (slider description, service title,) the quote (oftent used in French Language are replaced by backslash
Exemple: jusqu’à  replaced by jusqu\’à

each time i save one element, another slash is coming.

At the end, my homepage becomes : jusqu\\\\\\\\\’à 

i can only put the html code for the quote to avoid it >jusqu'à

How to avoid this please ? each time i have to replace this in every field when used. Thanks.
