/** @short A TQTextCodec for the UTF-7 transformation of Unicode.

|
|
This is a TQTextCodec for the UTF-7 transformation of Unicode,
|
|
described in RFC2152.
|
|
|
|
Use it as you would use any other TQTextCodec. Only if you use the
|
|
encoder directly (via makeEncoder), you should bear in mind
|
|
that if your application needs the encoder to return to ASCII mode
|
|
(like it's the case for RFC2047 mail header encoded words), you
|
|
have to tell the encoder by requesting the encoding of a @em null
|
|
TQString.

/** This is a version of @ref TQUtf7Codec, which should only be used in

MIME transfer. It differs from @ref TQUtf7Codec only in that the

encoder escapes additional characters (the RFC2152 "optional
|
|
direct set"), which might not be allowed in RFC822/RFC2047 header
|
|
fields.
|
|
|
|
You should only use this codec for @em encoding, since it's output
|
|
is pure UTF-7 and can equally well be decoded by @ref TQUtf7Codec's
|
|
decoder.
|
|
|
|
To distinguish between the two variants, this class has MIB enum
|
|
-1012 (the nagative of UTF-7) and the somewhat awkward name
|
|
"X-QT-UTF-7-STRICT". The MIME preferred charset name is still
|
|
"UTF-7", though.
