vtkDICOMParser cannot read DICOM files with non-ASCII characters in the filename about vtk-dicom HOT 7 CLOSED

That's unexpected, the parser should be able to read non-ascii filenames. Was this on Windows?

Did you try reading it with the command-line tools (dicomdump, dicomtocsv, etc) or are you using vtkDICOMParser from your own C++ program? Note that SetFileName() only takes ASCII or UTF-8, so if you give it any other encoding it will fail.

The DICOM command-line tools all use wmain() to get the command-line parameters as UTF-16, and then convert them to UTF-8 for use with the vtk-dicom API.

Yes, this was on Windows. The error either occurred when running dicomfind.exe or dicomdump.exe.

The error message was "ERROR: In E:\Kitware\vtk-dicom\Source\vtkDICOMParser.cxx line 1871 vtkDICOMParser (02EDEDD8): ReadFile: Can't open the file"

I have not been able to reproduce this issue. I've tried several languages and several tools (dicomfind.exe, dicomtocsv.exe, dicomdump.exe) and the special characters work fine for me, including a middle dot character:

dicomdump "F:\DICOM\画像CD発行システム‎\山田‧太郎.dcm"
==== F:\DICOM\画像CD発行システム‎\山田‧太郎.dcm ====
(0002,0000) UL "FileMetaInformationGroupLength" : [188] (4 bytes)
(0002,0001) OB "FileMetaInformationVersion" : [...] (2 bytes)
(0002,0002) UI "MediaStorageSOPClassUID" : [1.2.840.10008.5.1.4.1.1.7] {Secondary Capture Image Storage} (26 bytes)
(0002,0003) UI "MediaStorageSOPInstanceUID" : [1.3.6.1.4.1.5962.1.1.0.1.1.1175775771.5702.0] (44 bytes)
(0002,0010) UI "TransferSyntaxUID" : [1.2.840.10008.1.2.1] {Explicit VR Little Endian} (20 bytes)

Can you send me the exact text of the problem filename? A cut-and-paste from the console should work fine. No screenshots, since it's the code for the characters and not their appearance that matters.

Closing because I've tried to reproduce this problem, but files with special characters work fine for me. Will re-open if you can provide a .zip or .tar file with a DICOM file that demonstrates the problem.

My apologies, David. I also have not been able to reproduce the problem. Unfortunately, I couldn't get a copy of the original file that caused the problem. Thank you for looking into the issue. I'm flummoxed as to what was causing the issue on the user's PC.

Well, I think you mentioned before that you use vtkDICOMParser in C#? Are you sure the filenames are converted to utf-8 before you call SetFileName()?

But that doesn't explain why you would see problems with dicomdump and dicomtocsv, since these are pure C++ programs and they access the filesystem with UTF-16.
