There was a problem hiding this comment.
Instead of replacing the Unicode character, it might be cleaner to not produce it in the first place by executing Snapper with LC_ALL=C:
mybackupdir=$(LC_ALL=C snapper -c "$x" list -t single | awk -F"|" '/'"subvolid=$selected_subvolid, uuid=$selected_uuid"'/ {print $5}' | awk -F "," '/backupdir/ {print $1}' | awk -F"=" '{print $2}')(This might be something to consider at other places in the script too where the output of a command line tool is processed by the script.)
Additionally/alternatively, it might make sense to immediately restrict the output to the relevant column; however, this might not be backwards-compatible with older versions of Snapper:
mybackupdir=$(LC_ALL=C snapper -c "$x" list --columns userdata -t single | grep -F "subvolid=$selected_subvolid, uuid=$selected_uuid" | awk -F "," '/backupdir/ {print $1}' | awk -F"=" '{print $2}')
