The resource is not found (some of Customer)

Hi all,

I faced this problem

after I migrate ERPNext from 13 to 14 I have 19 Customer is not working
but I have document saved on those Customer such as Sales invoice and Sales order, but I can’t access to any of those customer or create a new sales invoice

I hope some one can help me…

after I search I found all those customer is contain Escape Char (), but in Version 13 is working fine but in Version 14 is not working

I also have some problems when Item Code contains / char in v13.
