UT should not parse its string argument

I see:

$ dcm-dump -v 1.3.6.1.4.1.36533.1001821602011442096713916118877991671060235.dcm

Regular dcmdump says:

$ dcmdump 1.3.6.1.4.1.36533.1001821602011442096713916118877991671060235.dcm | grep -i a160
    (0040,a160) UT [\\esmwz.europe.leicams.com\Images\2021-09-06\2_4_163906.svs] #  60, 1 TextValue
    (0040,a160) UT [PDX]                                    #   4, 1 TextValue

So it looks like it's parsing the (slightly unexpected) backslashes in the filename as multiple values.
