RFC2047:

...
 Generally, an "encoded-word" is a sequence of printable ASCII
 characters that begins with "=?", ends with "?=", and has two "?"s in
 between. It specifies a character set and an encoding method, and
 also includes the original text encoded as graphic ASCII characters,
 according to the rules for that encoding method.
...
 An 'encoded-word' may not be more than 75 characters long, including
 'charset', 'encoding', 'encoded-text', and delimiters. If it is
 desirable to encode more text than will fit in an 'encoded-word' of
 75 characters, multiple 'encoded-word's (separated by CRLF SPACE) may
 be used.
...
 Ordinary ASCII text and 'encoded-word's may appear together in the
 same header field. However, an 'encoded-word' that appears in a
 header field defined as '*text' MUST be separated from any adjacent
 'encoded-word' or 'text' by 'linear-white-space'.
