DICOM files import error of "Encoding is not supported" solution

[AstiMeowww]

I met a console error says :
"Problems processing the DICOM file D:/example.dcm :
openDicom.DicomException:
Encoding is not supported.
Context:
ParamName: characterSet
ParamValue: GB18030
StackTrace:
at openDicom.Encoding.CharacterRepertoire..ctor (System.String characterSet) [0x00479]"

Normally, if your platform is Windows or Linux, just enable SimpleITK and problem shall be solved. Bet I need to make DICOM reading work in android, and simply read the file in editor won't help because I need this function in realtime.
According to the error, it is because of the encoding of openDicom is limited to a couple of ISO standards, so I opened the encoding file "CharacterRepertoire.cs" in Assets\EasyVolumeRendering\Assets\3rdparty\openDicom\Encoding, add a case of encoding the GB18030 file in "switch (characterSet){}":

case "GB18030":
this.encoding = System.Text.Encoding.GetEncoding("GB18030");
break;

before the "default:" case.
I don't know if the GB18030 characters are really read by unity, but the import goes on and, at least, this problem is solved.
I think other than GB18030, any character encoding type not in the list of openDicom could be solved this way.
Hope this would help you.
