WGM with Inventor: how to map custom parameters from Inventor to Windchill if the parameter contains a special character like a spacing

I'm investigating the use of the WGM with Inventor.

The Inventor files carry a number of custom parameters of which some have a parameter name that contains a blank space, e.g. 'Treatment process"

Problem now is how to define a Windchill attribute (in version 10.2) so I can capture the value of this parameter.

Any parameter that has a name which does not carry a special character and so complies to the rules of Windchill attribute definition can be captured easily (either implicitly or explicitly).
