Cannot pass item with % symbol in sales and purchase

I was not able to edit an item created through purchase invoice screen with % symbol. It is showing a missing page . Please find the screen shot .It is a bug seemingly.Can anyone confirm ?

I have found this error in both ver 10 and ver 11 master

Yes this is a bug or defect - the search fails gracefully, without an error traceback to troubleshoot.

% is a ‘special character’ that probably should be restricted in an item name.

This will give you insight

More rigourous input validation and testing would screen for this case.

You may want to ‘scrub’ your data here.

EDIT: This is recent [v11] Why am I getting a Unicode Error in Production Server but not on my test environment for special characters?
