Member Function Documentation

QString QUtf16Decoder::toUnicode ( const char *  chars, int  len  )

inlinevirtual

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

If not all characters are used (eg. 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.

Implements QTextDecoder.
