# qtextdecoder(3qt)

State-based decoder

## NAME

QTextDecoder - State-based decoder

## SYNOPSIS

All the functions in this class are reentrant when Qt is built with thread support.\</p\>

`#include <qtextcodec.h>`

### Public Members

**virtual ~QTextDecoder ()**\
 **virtual QString toUnicode ( const char \* chars, int len ) = 0**\

## DESCRIPTION

The QTextDecoder class provides a state-based decoder.

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

See also QTextCodec::makeEncoder() and Internationalization with Qt.

## MEMBER FUNCTION DOCUMENTATION

## QTextDecoder::~QTextDecoder ()` [virtual]`

Destroys the decoder.

## QString QTextDecoder::toUnicode ( const char \* chars, int len )` [pure virtual]`

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.
