Summary0004314: When a non-ASCII character exists in the path a DICOM cannot be opened if only links are imported

When importing a DICOM into the DICOM database, the user has to choose if the data or only links should be added to it.
If the user chooses to add only links (so that data is not necessarily duplicated in the file system) AND the path contains a non-ASCII character (like á,í,?,?,ü,ö,ú,ó,é) then the import seemingly goes okay but when the user tries to open any series from that patient an error pops up, saying:
"Warning: Plugin failed: MultiVolumeImporterPlugin
See python console for error message"

After clicking OK, the error popup is dismissed and the Processing... window pops up but it effectively stays at 0% as long as it is cancelled.

See the Python output in the "Additional information"

If DICOM data is imported, not just the links are added, then things work as expected.

Also if the non-ASCII characters are removed from the path then after deleting and re-importing the same DICOM series, data can be loaded even if "Add link" is selected.

Steps To Reproduce

1.) Import any DICOM (I downloaded one example dataset from but the problem does not depend on the data)
1.5.) Put it in a subdirectory or path that contains any of the above "weird" :) characters. Or try this word: próba
2.) Chose "Add link" when importing the DICOM
3.) Select patient and choose a study/series to load

Additional Information

In the Python console it reads:

I can replicate this issue on my windows 10 computer based on the steps provided.

Possible solution: It would be good to move the SlicerWizard utility code that uses the chardet python package into the main slicer.util space so that it could be used in dicom plugins.
