Description
Currently, the oficonv implementation of character set conversion will silently accept two-byte Shift-JIS characters when ISO_IR 13 (JIS X0201) is active as the current input character set. Shift-JIS is true superset of JIS X0201 (which by itself is a single-byte character set). DICOM does not support Shift-JIS. It would be preferrable thus if oficonv would report an error in these cases, like the GNU libiconv implementation does.
In the attached sample file,- attribute (0010,4000) contains the byte sequence "b1\41\5c\1b\24\42\25\22\23\41\21\40", which is a valid ISO 2022 ISO_IR 13/ISO 2022 ISO_IR 87 string.
- attribute (0020,4000) contains the byte sequence "b1\41\5c\83\41\82\60\81\5f". This generates the same Kanji characters though Shift-JIS codes, which are not allowed in DICOM.
Dump the file with dcmdump +U8 shift_jis_example.dcm to demonstrate the effect.
