You did not make that clear: I now see where your problem is.

Well, I'm afraid that's not exactly "more realistic".  If you put a URL in an
HTML document then *you* are responsible for writing it correctly for the
browser to use, to encode the characters for transmission to the server.

So your HTML is incorrect and should be

<li><a href="file:///RAM::RamDisc0/$/test/Text2%EA">Go through to html</a>

Browsers vary as to how much they handle conversion of characters which
should not be present in links.  Did you inform NetSurf which character set
was in use in the HTML file by using the correct meta tag attributes in the
head of the file, or by serving it from a web server which gave the character
set in the HTTP response?

And if you're expecting it to cope with the bullet, when the default
character set for HTML documents is ISO Latin 1, which does not have a bullet
character, think again!  That's certainly going to be a low priority for the
developers.

If you are writing the HTML yourself, and have control over the encoding of
top-bit-set characters, then what's the problem?  You just need to write the
HTML better.

Quote me the relevant bit of the HTML standards.  By that token you would
expect any % appearing in an href attribute to be encoded as %25 but I can
assure you that no mainstream browsers do this.  The href attribute is first
decoded from HTML (for example, converting any "&amp;" to "&") and then
offered to the server as it is.
