Fixed an issue with setting certificates when the common name contained non-ASCII characters, like:
Apple Distribution: xyz (ä) (xyz).
The Xcode Archive Stap failed with:
error: No certificate for team 'xyz' matching 'Apple Distribution: xyz (î) (xyz)' found: Select a different signing certificate for CODE_SIGN_IDENTITY, a team that matches your selected certificate, or switch to automatic provisioning. (in target 'App' from project 'App')
