### Public Functions

- QTextDecoder ( const QTextCodec * codec )
- ~QTextDecoder ()
- QString toUnicode ( const char * chars, int len )
- QString toUnicode ( const QByteArray & ba )

## Detailed Description

The QTextDecoder class provides a state-based decoder.

A text decoder converts text from an encoded text format into Unicode using a specific codec.

The decoder converts text in this format into Unicode, remembering any state that is required between calls.

See also QTextCodec::makeDecoder() and QTextEncoder.

## Member Function Documentation

### QTextDecoder::QTextDecoder ( const QTextCodec * codec )

Constructs a text decoder for the given codec.

### QTextDecoder::~QTextDecoder ()

Destroys the decoder.

### QString QTextDecoder::toUnicode ( const char * chars, int len )

Converts the first len bytes in chars to Unicode, returning the result.

If not all characters are used (e.g. if only part of a multi-byte encoding is at the end of the characters), the decoder remembers enough state to continue with the next call to this function.

### QString QTextDecoder::toUnicode ( const QByteArray & ba )

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

Converts the bytes in the byte array specified by ba to Unicode and returns the result.
