Problem with ODATA URL Dynamics NAV

Hi

I have a problem with my OData URL for NAV. The problem lies in that my company name contains a / in the end like

'My Company A/S'

I have tried but it wont connect.

http://url.com/NAVWS/OData/Company('My%20Company%20A%2FS')

http://url.com/NAVWS/OData/Company('My%20Company%20A/S')

I have a company without A/S and that works fine, any ideas?
