| 64 | This module performs quoted-printable transport encoding and decoding, | |
| 65 | as defined in <a class="rfc" id='rfcref-91270' xml:id='rfcref-91270' | |
| 66 | href="http://www.faqs.org/rfcs/rfc1521.html">RFC 1521</a>: ``MIME (Multipurpose Internet Mail | |
| 67 | Extensions) Part One: Mechanisms for Specifying and Describing the | |
| 68 | Format of Internet Message Bodies''. The quoted-printable encoding is | |
| 69 | designed for data where there are relatively few nonprintable | |
| 70 | characters; the base64 encoding scheme available via the | |
| 71 | <tt class="module"><a href="module-base64.html">base64</a></tt> module is more compact if there are many such | |
| 72 | characters, as when sending a graphics file. | |

| 84 | <code><var>input</var>.readline()</code> returns an empty string. | |
| 85 | If the optional argument <var>header</var> is present and true, underscore | |
| 86 | will be decoded as space. This is used to decode | |
| 87 | ``Q''-encoded headers as described in <a class="rfc" id='rfcref-91273' xml:id='rfcref-91273' | |
