How to escape filenames with special characters

[dbuijs]

The command line mc utility will accept minio filenames with special characters in them as long as the whole path is contained within single quotes '

The R command mc_ls() will return filenames with spaces and special characters in them, but using these strings in mc_cat() returns an error.
