 opustags is designed to be fast and as conservative as possible, to the point that if you edit tags

 opustags is tag-agnostic: you can write arbitrary key-value tags, and none of them will be treated
 specially. After all, common tags like TITLE or ARTIST are nothing more than conventions.
 
-It currently has the following limitations:
-
-- The total size of all tags cannot exceed 64 kB, the maximum size of one Ogg page.
-- Multiplexed streams are not supported.
-- Newlines inside tags are not supported by `--set-all`.

-If you'd like one of these limitations lifted, please do open an issue explaining your use case.
-Feel free to ask for new features too.

 opustags supports. If your system encoding is different, the tags are automatically converted to and
