• Support for non-Unicode systems. Tags are automatically converted to and from the system locale.
• It is now possible to delete specific NAME=VALUE pairs.
• Option --set-all is now stricter and aborts with an error if the input is not valid.
• Printing tags will display a warning if the tags contain control characters.

opustags is now more aware of its limitations, and will print more helpful error messages when
trying to edit an unsupported file. It is also more cautious against corrupted streams.
