Use the MIMEHEADER_ENCODE function to convert a string into mime header format and then encode the string. The signature is:

MIMEHEADER_ENCODE(<buf> IN VARCHAR2, <encode_charset> IN VARCHAR2

 =?UTF8?Q?What is the date??=
(1 row)

edb=# SELECT UTL_ENCODE.MIMEHEADER_DECODE('=?UTF8?Q?What is the date??=')
