You can use StringEscapeUtils.unescapeHtml4 for this.

For example, the string "<Français>" will become "<Français>"

You need to know how it was encoded to reverse it.

If it was URL encoded (which looks likely) then Java has a built in URLDecoder class.

URLDecoder.decode(message, encoding);

Apache Commons provides utilities for this.

org.apache.commons.lang.StringEscapeUtils.unescapeHtml(String string) should be what you want.
