Uh, no. It's for both directions.
If I want my web server to find the resource named "Randal's File.txt",
I cannot include:
<a href="Randal's File.txt">Get my file!</a>
as an anchor. I need to URI encode the filename:
<a href="Randal%27s%20File.txt">Get my file!</a>
The browser returns that link as-is (minus HTML entities, see below),
requesting something like "GET /some/place/Randal%27s%20File.txt HTTP/1.0" in
the request. The web server "de URIs" it, and gets the real name with the
spaces.
C> HTML encoding is for HTML, from the web server to the browser.
Yes, and that also includes attributes. If I wanted to run "Randal's
File.cgi", passing it both fred=flintstone and barney=rubble as
parameters, using an ampersand for a delimiter, I'd construct the URI as:
Randal%27s%20File.txt?fred=flintstone&barney=rubble
and *then* I'd have to HTML-entitize that (& becomes &):
<a href="Randal%27s%20File.txt?fred=flintstone&barney=rubble">gimme!</a>
For this, the browser will request back to the server:
GET /some/place/Randal%27s%20File.cgi?fred=flintstone&barney=rubble HTTP/1.0
because the protocol is URI-encoded, but not HTML encoded.
This is why the advice is as it is in the docs. Filenames have to be URI
encoded if part of a URI, and *everything* has to be HTML-ized.
