My XML file with encoding UTF-8:

<?xml version="1.0" encoding="UTF-8" ?>

<chart baseFont="Arial" baseFontSize="11" hoverCapBgColor="F0F0F0" hoverCapBorderColor="A5CFE9" hoverCapSepChar="" chartTopMargin="40" isSliced="1" decimalPrecision="2" numberSuffix="K%80">

<set name="Négociation" value="10.5000000000"  />

<set name="Offre" value="0.0000000000" />

</chart>

On the generated graph :

- € : ok

- é : é <==== ?????

Why ? Any idea ? :o(

Thanks.
