Yes, all reservered characters must be replaced with %HH where HH is the

A space is %20 in a URL.

When you create a URL you need to escape each individual part of the URL and
then append them all and create the URL with the proper "part" separators.
Like for directory names you need to escape the names but then join them with
a slash separating them.

No. The *QUOTE options are plain strings you send to the FTP server unmodified
and untouch by libcurl. You need to send those strings to the server in a
format that the server expects and wants them to be. That is actually a much
less defined area. RFC959 is not at all very clear on how to encode "weird"
characters. At least I didn't find it the last time I checked.
