How to avoid invalid charators while loading the scheduler ?

I am getting invalid xml error if the data to be populated in scheduler contains non alphanumeric characters, i suppose it occurs due to insertion from non US standard keyboards such as spanish…
Is there any method to avoid such cases in the scheduler itself

am using scheduler 2.1


For now I can only give general advice — you need to make sure that everywhere (database, server, request, response) utf-8 is correctly handled.

Also you can try updating to the latest version (2.3).
