Hi, Cyphre,
It is easier to explain how to bypass the problem than to explain where the
real problem lies.
:)
The problem seems to be that the percent sign can be used to escape hex
coded characters. The dehex-ed character for C8 is È. When the url is
entered, the interpreter immediately substitues the character "È" for "%C8".
However, the url parser will no longer parse the entire url, because "È" is
not a part of its rules. Probing the http scheme *after* a failed read
shows that the file portion contains the fragment "?co=naslepo&kde=A-",
indicating to me that it failed at the next character, which *it* thinks is
"È" instead of "%" (followed by "C8", of course).
The way to work around the problem is to do something like the following:
read rejoin [http://slovnik.nettown.cz/?co=naslepo&kde=A- "%C8"]
which then returns the page.
What I am unsure about is exactly "where" the problem lies? Is it that some
urls contain hex encoded characters and that REBOL improperly translates the
results in an incorrect manner? I do not know for sure. I am not sure why
my work-around works! Unfortunately, I am out of time to explore the
problem further right now.
Hope this helps a bit anyway.
