Related The QTextCodec should always be constructed on the heap i. Qt takes ownership and will delete it when the application terminates. Destroys the QTextCodec. Note that you should not delete codecs yourself: once created they become Qt's responsibility. Standard aliases for codecs can be found in the IANA character-sets encoding file. Returns the list of all available codecs, by name. See also availableMibs , name , and aliases. Returns the list of MIBs for all available codecs.

See also availableCodecs and mibEnum. Returns true if the Unicode character ch can be fully encoded with this codec; otherwise returns false. If this function returns 0 the default , QString assumes Latin Tries to detect the encoding of the provided snippet of HTML in the given byte array, ba , by checking the BOM Byte Order Mark and the content-type meta header and returns a QTextCodec instance that is capable of decoding the html to unicode.

If the codec cannot be detected from the content provided, defaultCodec is returned. If the codec cannot be detected, this overload returns a Latin-1 QTextCodec. On Windows, the codec will be based on a system locale.

On Unix systems, starting with Qt 4. Note that in both cases the codec's name will be "System". Searches all installed QTextCodec objects and returns the one which best matches name ; the match is case-insensitive. Returns 0 if no codec matching the name name could be found. Returns the codec used by QObject::tr on its argument. If this function returns 0 the default , tr assumes Latin Tries to detect the encoding of the provided snippet ba by using the BOM Byte Order Mark and returns a QTextCodec instance that is capable of decoding the text to unicode.

Converts the first number of characters from the input array from Unicode to the encoding of the subclass, and returns the result in a QByteArray.

If state is not 0, the codec should save the state after the conversion in state , and adjust the remainingChars and invalidChars members of the struct. Converts the first len characters of chars from the encoding of the subclass to Unicode, and returns the result in a QString. Converts str from Unicode to the encoding of this codec, and returns the result in a QByteArray. Converts the first number of characters from the input array from Unicode to the encoding of this codec, and returns the result in a QByteArray.

Subclasses of QTextCodec must reimplement this function. See Documentation for the built-in codecs. These built-in codecs are instantiated on startup and get registered with the Qt's codec system. The local 8-bit codec can convert from unicode to the character set specified in the locale and vice versa.

This codec is called the "System" codec. On Unix, coversion is done using iconv. The codec detected has to be a part of the Qt built-in codec list Otherwise, it defaults to latin
