This module handles the content transfer encoding method defined in RFC 2045 to encode US ASCII-like 8-bit data called `quoted-printable'. It is used to safely encode text that is in a character set similar to the 7-bit US ASCII character set, but that includes some 8-bit characters that are normally not allowed in email bodies or headers. Quoted-printable is very space-inefficient for encoding binary files; use the email.base64mime module for that instead. This module provides an interface to encode and decode both headers and bodies with quoted-printable encoding. RFC 2045 defines a method for including character set information in an `encoded-word' in a header. This method is commonly used for 8-bit real names in To:/From:/Cc: etc. fields, as well as Subject: lines. This module does not do the line wrapping or end-of-line character conversion necessary for proper internationalized headers; it only does dumb encoding and decoding. To deal with the various line wrapping issues, use the email.header module. u body_decodeu body_encodeu body_lengthu decodeu decodestringu header_decodeu header_encodeu header_lengthu quoteu unquotei N( u ascii_lettersu digitsu hexdigitsu u u c C s g | ] } d | � q S( u =%02X( ( u .0u c( ( u5 /opt/alt/python33/lib64/python3.3/email/quoprimime.pyu <listcomp>8 s u <listcomp>i s -!*+/u asciiu _u s_ !"#$%&'()*+,-./0123456789:;<>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~ c C s t | � t | k S( u> Return True if the octet should be escaped with header quopri.( u chru _QUOPRI_HEADER_MAP( u octet( ( u5 /opt/alt/python33/lib64/python3.3/email/quoprimime.pyu header_checkK s u header_checkc C s t | � t | k S( u< Return True if the octet should be escaped with body quopri.( u chru _QUOPRI_BODY_MAP( u octet( ( u5 /opt/alt/python33/lib64/python3.3/email/quoprimime.pyu body_checkP s u body_checkc C s t d d � | D� � S( u: Return a header quoted-printable encoding length.

Defined in RFC 2045, this `Q' encoding is similar to quoted-printable, but used specifically for email header fields to allow charsets with mostly 7 bit characters (and some 8 bit) to remain more or less readable in non-RFC 2045 aware mail clients. charset names the character set to use in the RFC 2046 header.

Each line of encoded text will end with eol, which defaults to "\n". Set this to "\r\n" if you will be using the result of this function directly in an email. Each line will be wrapped at, at most, maxlinelen characters before the eol string (maxlinelen defaults to 76 characters, the maximum value permitted by RFC 2045). Long lines will have the 'soft line break' quoted-printable character "=" appended to them, so the decoded text will be identical to the original text. The minimum maxlinelen is 4 to have room for a quoted character ("=XX") followed by a soft line break. Smaller values will generate a ValueError. i u maxlinelen must be at least 4u =i i i u i Nu i����i����i����i����i����i����( u ValueErroru translateu _QUOPRI_BODY_ENCODE_MAPu appendu splitlinesu lenu quoteu CRLFu join( u bodyu maxlinelenu eolu soft_breaku maxlinelen1u encoded_bodyu appendu lineu startu laststartu stopu roomu q( ( u5 /opt/alt/python33/lib64/python3.3/email/quoprimime.pyu body_encode� sD c C s� | s | Sd } x8| j � D]*} | j � } | sE | | 7} q n d } t | � } x� | | k rF| | } | d k r� | | 7} | d 7} n� | d | k r� | d 7} qZ nw | d | k r| | d t k r| | d t k r| t | | | d � � 7} | d 7} n | | 7} | d 7} | | k rZ | | 7} qZ qZ Wq W| d d k r}| j | � r}| d d � } n | S( u_ Decode a quoted-printable string.
