Re: Get and substitute filenames of filepathes that contain umlauts/special chars

yes, your interpretation is correct. I would suggest to export the
commands to a sed script, one command per line. One command per line is
more clear when you have a long list of replacements.

There was a discussion on the y command recently.  Not sure if there are
drawbacks so I would stick to s command
