I'm trying to use the ASP.NET chart controls for a website that is localised for number of languages. However, we've had issues with the charts when we recently added a Chinese localisation - all of the labels show squares where we actually want Chinese characters, as shown in my sample below (please note I don't know any Chinese so this could be saying anything):
default.aspx (no code behind):
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="ChineseChart._Default" %>
<%@ Register Assembly="System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
Namespace="System.Web.UI.DataVisualization.Charting" TagPrefix="asp" %>

</asp:Chart>
</div>
</form>
</body>

Chart Generated:
This to me points to a character encoding issue, but I can't find anything in the chart object to change the encoding of the control.
Is there any way I can fix this issue?
Update: We also have this website in Greek & Hebrew, & neither of these languages are causing us any issues on the charts.
