External .js with alert() not displaying french accent properly!?

[ltrem]

Hi try to do some alert inside an .js... the alert work fine... but the french accent character is wrong.

 

I do something like

 

alert('Salut à toi mon ami!');

 

But the "à" is displayed like an square with a ? inside.

 

I need to replace the "à" with "\xE0" for it to work... which is hexa...

 

now is there a function I could use? Thx
