Titles of Linked RFCs with Apostrophes are not Properly Escaped

[rcarver3]

Describe the issue

When hovering over a link to an RFC, the title of the linked RFC is shown in a tooltip. If the displayed title contains an apostrophe ("), the rest of the title is not displayed. If I had to guess, this is due to an improper character escape. The following screenshots were taken from Firefox 150.0.1 (32-bit).

In this example, the title of the linked RFC is:

Deprecating the "X-" Prefix and Similar Constructs in Application Protocols

In this example, the title of the linked RFC is:

Update to MIME regarding "charset" Parameter Handling in Textual Media Types

This screenshot shows the expected output of a tooltip. The title contains no apostrophes and therefore renders correctly in the hover tooltip.

This occurs both at https://www.rfc-editor.org/rfc/rfc6838.html and at https://datatracker.ietf.org/doc/html/rfc6838 - as these are pre-v3-era documents, this html is the output of rfc2html (and is known as htmlized), and the bug likely lives there.

For instance, the htmlized output contains:

considered to be members of this tree (see [<a href="[./rfc6648](view-source:https://www.rfc-editor.org/rfc/rfc6648)" title="&quot;Deprecating the &quot;">RFC6648</a>]).  Also note

I'll transfer the issue to rfc2html.
