The files that you attached suffer from the same issue (incorrect SpecificCharacterSet value) as those that you provided earlier. Please contact the manufacturer of the device/software that produced these files, as they are incorrect.
DICOM patcher’s Specify character set rule fixed most of these files, except those where the SpecificCharacterSet field was not just missing, but it contained incorrect value. I’ve submitted a pull request that makes the patcher rule even stronger - if that is integrated then the Force character set rule will become available in DICOM Patcher module and you can fix all these flawed files and load them into Slicer with correct patient names.
Loading files that are stored in path that contained special characters: I’ve already submitted a fix, but it has not been integrated yet. @jcfr please have a look.
