MimeEncodeWord function

Generate a MIME 'encoded word' for use in mail headers (RFC 2047)

function MimeEncodeWord ($str, $quote_plain = false, $force_b64 = false, $charset = 'ISO-8859-1');

Parameters:

str

quote_plain – optional, default: false

force_b64 – optional, default: false

charset – optional, default: 'ISO-8859-1'

Return value:

either the plain string or an 'encoded word'

Remarks:

checks which encoding (quoted-printable/base64) is more efficient in this case and
since quoted_printable_encode is used, this function is NOT BINARY SAFE!
set ($force_b64 = true) to reliably encode binary data here

($quote_plain = true) encloses plain (unchanged) text in "" chars
