How to manage special characters (UTF-8) with Fiji Charts ?

Hello,

I'm using a component in a JSF application.
But special character like é or à are not properly displayed. I have searched for a workaround, but I found nothing.
Do you know a solution to setting the UTF-8 encoding ?

Here is an example of my JSF code ( I have removed tags, because this forum editor doesn't allow this tags) :

fiji:columnChart id="columnChartOneOrdersByStatus" value="#{chartBean.ordersByStatus.dataMap}"
title="#{msg.GRAPH_NBR_ORDER_BY_STATUS}"
barCaption="none"
barColors="#{chartBean.ordersByStatus.colors}"
captionY="#{msg.GRAPH_NBR_ORDER_BY_STATUS_AXE_Y}"
toolTipValue="#{msg.GRAPH_NBR_ORDER_BY_STATUS_TOOLTIP}"
subtitle="#{msg.GRAPH_NBR_ORDER_BY_STATUS}" width="400" height="300">
fiji:chartData type="name" value="#{chartBean.ordersByStatus.names}"

fiji:columnChart

Thank's !
