The "title*" parameter can be used to encode the title label in a different character set, and/or contain
language information as per <a href="https://tools.ietf.org/html/rfc5987">RFC-5987</a>.  The "title*" parameter MUST NOT appear more than once in a given
link-value; occurrences after the first MUST be ignored by parsers.  If the parameter does not contain language
information, its language is indicated by the Content-Language header (when present).
<p>
If both the "title" and "title*" parameters appear in a link-value, processors SHOULD use the "title*"
parameter's value. <p>The example below shows an instance of the Link header encoding a link title using <a href="https://tools.ietf.org/html/rfc2231">RFC-2231</a>
encoding to encode both non-ASCII characters and language information.</p>
