+
+ This is a QTextCodec for the UTF-7 transformation of Unicode,
+ described in RFC2152.
+
+ Use it as you would use any other QTextCodec. 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
+ QString.

+ 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 QUtf7Codec'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.
