It took me a lot of time to figure out why my program didn't behave as expected....

Two separate issues.

There appears to be a bug in FBtoC that allows the below enumeration.  The constants are listed twice and are incremented accordingly.
As an example, the constant  _kCFCharacterSetDecimalDigit  should have a value of 4, however with the below definition, it is 6.

This header definition, located in " Tlbx CFCharacterSet.incl" is incorrect because of the repeated constants
