An encapsulated Data Set shall only include the Specific Character Set (0008,0005) Data Element if the Specific Character Set (0008,0005) is defined in the IOD for that Sequence of Items.

If an encapsulated Data Set includes Specific Character Set (0008,0005), it shall apply only to the encapsulated Data Set. If Specific Character Set (0008,0005) is not explicitly included in an encapsulated Data Set, then the Specific Character Set (0008,0005) Value of the encapsulating Data Set applies.
