I notice that LOAD seems to be doing something interesting with that percent-escaped character at the end, and possibly transforming it into a character that's not legal for a URL (prematurely?).

== {<!doctype html public "-//w3c//dtd html 3.2 final//en"> <!-- Copyright (C) 2000 Petr Kýra, [kura--nettown--cz] All rights reserved...
>> read load "http://slovnik.nettown.cz/?co=naslepo&kde=A-%C8"
** User Error: URL error: http://slovnik.nettown.cz/?co=naslepo&kde=A-» ** Near: read load "http://slovnik.nettown.cz/?co=naslepo&kde=A-%C8" Notice that the message is User Error: URL error: ... and not Syntax Error: Invalid url ... as in
>> read load "http://%"
** Syntax Error: Invalid url -- http://% ** Near: (line 1) http://% implying to my eye that LOAD was happy but the result wasn't usable by READ. When I say something like
>> gorp: "http://%77%77%77.rebol%2ecom/"
== "http://%77%77%77.rebol%2ecom/"
>> load gorp
== http://www.rebol.com/ LOAD seems to want to unescape the string. That's OK in this case, since all of the escaped characters are actually valid in URLs, but in the case of

== "http://slovnik.nettown.cz/?co=naslepo&kde=A-%C8"
>> load bletch
== http://slovnik.nettown.cz/?co=naslepo&kde=A-» the (premature) unescaping of "%C8" back to the high-bit-on accented-E character may be the source of grief when that literal character is deemed invalid for use in a URL. Hope this helps!!! -jn-
