UTF-7, like UTF-8 and UTF-16, encodes all of the Unicode repertoire. You don't
need to understand RFC 2060 completely unless you're going to write your own
IMAP-compatible software. What I meant by "yes and no" was that you can't use
UTF-8-encoded folder names as arguments to maildirmake or deliver, or in
Sieve scripts - you have to use a MUA (such as Thunderbird) or other program
that can encode the folder name properly.

Thunderbird will use the separator that the IMAP server tells it to when
talking to the IMAP server. However, Dovecot doesn't encode slashes or dots
in any special way, so neither can be used in folder names regardless of
wether slash or dot is the separator.
(If "/" is the separator and you try to create a folder called "Foo.Bar",
Dovecot will (with a common configuration) create ~/Maildir/.Foo.Bar, which
looks like a folder Foo with a subfolder Bar. If the separator is "." and you
try to create a folder called "Foo/Bar", then Dovecot will or will not try to
create ~/Maildir/.Foo/Bar, which in any case won't work.)
