Bad display of Πcharacter in Click Components

[easydoor958]

Hi all,

I meet some difficulties to display the Πcharacter (OELig;) in a Click Page. 
When I put this character directly in the HTML page, it displays well but 
if i put this one in the Java Controller in a Table or in TextArea,
this one is displayed as ?

Does it mean that Click components doesn't traduce extended characters
(ISO-8859-15) ?

Thanks for your reply
