Hello,

I have faced the same issue when I am creating a product name with '中文产品' and try to print 'Stock level forecast' report.

@Assigned Team : Would you please checked lp:1007854 and lp:956798.

Thank you!

This bug doesn't belong to OpenERP, it's a problem from PYCHART.
PYCHART is a library that provides chart and legend but unfortunately this library doesn"t handle special utf-8 characters such as chinese and korean.
As we will not fix the PYCHART library, we decided to catch those special characters and we replace them by "?" to avoid a crach.

Good luck to everyone,
