Problem

If event attribute value contains $ then value is discarded starting from $ until end of the value in Unix.
If event attribute value contains % then only % is discarded in Windows.

Resolution

On Unix:
./TRKUTIL SendEvent OBJNAME=<TrackingObject_Name>,<Attribute_Name>=Fou'$$'rth

This will insert Fou$rth as attribute value

On Windows:
TRKUTIL SendEvent OBJNAME=<TrackingObject_Name>, <Attribute_Name>=Fo%%urth

This will insert Fo%urth as attribute value
