When creating Ibexa PIM products via PHP, illegal characters go undetected when creating choices for selection attribute. The same literals would be rejected by Ibexa's admin UI.

This leads to come crash with an error:

The name "w/ outlet" contains illegal characters. Names should start with a letter, digit or underscore and only contain letters, digits, numbers, underscores ("\_"), hyphens ("-") and colons (":"). 

Actually, I think this was an issue for the key/identifier, and not for the label, but if it was for the label, it's even worse - why wouldn't we allow special characters in labels?
