unpack is a tool, you can invent basically any format which is suitable for your needs and it will be fairly easy to encode and decode.
base64 looks like this:
SSB3aXNoIHlvdSBjb3VsZCB0cnkgdGhpcyB5b3Vyc2VsZgo=
It's what's used inside email messages for attachments if you "view source" (or are old enough to telnet to your IMAP server :-)
quoted-printable replaces any non-ascii with an escape code, consisting of an equals sign and a hex code, =3Dlike this=3D (just to give you an idea).
You really need to give more details to work on, or just pick one.

MIME::QuotedPrint(3perl) Perl Programmers Reference Guide MIME::QuotedPrint(3perl)
NAME
MIME::QuotedPrint - Encoding and decoding of quoted-printable strings
SYNOPSIS
use MIME::QuotedPrint;
$encoded = encode_qp($decoded);
$decoded = decode_qp($encoded);
DESCRIPTION
This module provides functions to encode and decode strings into and from the quoted-printable encoding specified in RFC 2045 - MIME
(Multipurpose Internet Mail Extensions). The quoted-printable encoding is intended to represent data that largely consists of bytes that
correspond to printable characters in the ASCII character set. Each non-printable character (as defined by English Americans) is
represented by a triplet consisting of the character "=" followed by two hexadecimal digits.
The following functions are provided:
encode_qp( $str)
encode_qp( $str, $eol)
encode_qp( $str, $eol, $binmode )
This function returns an encoded version of the string ($str) given as argument.
The second argument ($eol) is the line-ending sequence to use. It is optional and defaults to "
". Every occurrence of "
" is
replaced with this string, and it is also used for additional "soft line breaks" to ensure that no line end up longer than 76
characters. Pass it as "
