The "garbage" you are seeing in the raw emails is MIME encoding for non-ascii 
characters. =20 and other such sequences are the quoted-printable transfer 
encoding.
It is not "garbage", encoding of email messages is necessary to display non-
ASCII characters. Every email program in the world should support that. Why 
are you looking at the raw mail?

If the mail only uses some subset of ASCII characters, then 7bit encoding can 
be used. Only when the mails have non-ASCII characters, some sort of encoding 
will be used, for example quoted-printable as shown above.

Yes. In the composer, manually choose that encoding in Options->Set Encoding. 
It is also somewhere in the config menu.

Everything else than the characters shown in the first table of 
http://www.asciitable.com/ will need special encoding.

You should really not worry about encoding issues, using non-ASCII characters 
is understood by virtually every mail client today, MIME encodings like 
qouted-printable have been around for more than a decade.
