It expects the input file to be UTF-8 now. So I've added that the plugin help text in https://github.com/openjdk/jdk/pull/28399/commits/2f48c81b90e358dabd01b96a89e2dcc9d882c781

It's the plugin that creates the `$JDK/release` file. That's it.

I've added it to the `--list-plugin` help text now. Plugins aren't mentioned in the `jlink` man page, so it doesn't seem appropriate to mention it the `jlink` man page. Here is how it looks like when using `jlink --list-plugins` with the latest update:


  --release-info <file>|add:<key1>=<value1>:<key2>=<value2>:...|del:<key list>
                            <file> option is to load release properties from
                            the supplied file. The specified file is expected
                            to be encoded in UTF-8.
                            add: is to add properties to the release file.
                            Any number of <key>=<value> pairs can be passed.
                            del: is to delete the list of keys in release file.
