Export to CSV

Dear Experts,

We are on BI 7.0 and we came across the following problem :

When we wre exporting to CSV from Web template in Portal, each £ sybmol is accompanied by  

ie.£ 1500 (where it should have been £1500).

When exporting to Excel/ excel 2000, it is working fine. And we export it Excel and save it as CSV, it's showing the values with £ sign only. But my client is not happy to export to Excel and then save it to CSV.

Has anyone come across with this?

Is there an outstanding update / OSS Note / patch etc. from SAP to correct this issue?Or is it more likely  IMG seetings issue ?

Thanks
