Special characters not allowed in K2 artifact names

When you name K2 artifacts such as workflows, SmartObjects, forms, views, roles, or other artifacts where you can specify a name or value, special characters may not be allowed, display, or work as expected. In general, try not to use non-letter or non-number characters when naming these items. 

For information on specific and known character restrictions, please see the article KB002544 - Item Naming: Known Restrictions and Limitations.
