The value of Specific Character Set (0008,0005) in the Image and the Hanging Protocol Instance may differ and shall be taken into account for matching.
The value of Specific Character Set (0008,0005) may influence how matching of text Attributes is performed, in an implementation dependent manner. No requirements are specified for case sensitive or accent sensitive matching, or for ignoring padding.
The matching shall be performed on Coding Scheme Designator (0008,0102) and Code Value (0008,0100). The Code Meaning (0008,0104) is required to be present, but shall be ignored for matching purposes. The matching is case sensitive, and leading and trailing spaces are not significant. The Coding Scheme Version (0008,0103) shall be ignored unless Coding Scheme Designator (0008,0102) is not sufficient to identify the Code Value (0008,0100) unambiguously.
