convertToUnicode() [1/6]

char16_t * QUtf8::convertToUnicode ( char16_t *  dst, QByteArrayView  in  )

staticnoexcept

Since

6.6 This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Converts the UTF-8 sequence of bytes viewed by in to a sequence of QChar starting at dst in the destination buffer. The buffer is expected to be large enough to hold the result. An upper bound for the size of the buffer is in.size() QChars.

If, during decoding, an error occurs, a QChar::ReplacementCharacter is written.

Returns a pointer to one past the last QChar written.

This function never throws.

For QChar buffers, instead of casting manually, you can use the static QUtf8::convertToUnicode(QChar *, QByteArrayView) directly.
