The DICOM character encoding is determined automatically from the element with tag '0008,0005' (Specific Character Set) - if present. The following character sets are currently supported (requires libxml to include iconv support, see --version output):

ASCII         (ISO_IR 6)    (UTF-8)
UTF-8         "ISO_IR 192"  (UTF-8)
ISO Latin 1   "ISO_IR 100"  (ISO-8859-1)
ISO Latin 2   "ISO_IR 101"  (ISO-8859-2)
ISO Latin 3   "ISO_IR 109"  (ISO-8859-3)
ISO Latin 4   "ISO_IR 110"  (ISO-8859-4)
ISO Latin 5   "ISO_IR 148"  (ISO-8859-9)
Cyrillic      "ISO_IR 144"  (ISO-8859-5)
Arabic        "ISO_IR 127"  (ISO-8859-6)
Greek         "ISO_IR 126"  (ISO-8859-7)
Hebrew        "ISO_IR 138"  (ISO-8859-8)

Multiple character sets are not supported (only the first value of the 'Specific Character Set' is used for the character encoding in case of value multiplicity).

See dcm2xml documentation for more details on the XML structure.

Binary data (*) can be encoded either as a sequence of hex numbers separated by a backslash '\' or in Base64 format (binary='base64'). In addition, binary data can also be read from file (binary='file'). In this case, the filename has to be specified as the element value, e.g.

<element tag="7fe0,0010" vr="OW" ... binary="file">subdir/pixeldata.raw</element>

Please note that the contents of the file will be read as is. OW data is expected to be little endian ordered and will be swapped if necessary. No checks will be made to ensure that the amount of data is reasonable in terms of other attributes such as Rows or Columns.

(*) Please note that currently only OB and OW data is supported, i.e. element values with a VR of OD, OF, OL and OV are not regarded as 'binary data' and treated as all other VRs.

If libxml is compiled with zlib support, the input file (xmlfile-in) can also be compressed with ZIP, which usually results in much smaller files. See output of option --version in order to check whether zlib support is available.

Different versions of libxml might have different limits for the maximum length of an XML element value. Therefore, it should be avoided to use very long element values (e.g. for pixel data).

Please note that xml2dcm currently does not fully support DICOMDIR files. Specifically, the value of the various offset data elements is not updated automatically by this tool.
