[Interest] Filling QString from raw UTF16 data

[Konstantin Tokarev]

Hi all,

I'd like to use SCSU encoding from ICU library in my Qt application. Here is a code of my decoding function:

    QString result;
    result.resize(maxSize); // maxSize is guaranteed to be >= size
    const int size = ucnv_toUChars(m_converter, const_cast<ushort *>(result.utf16()), maxSize, a, inSize, &status);
    result.resize(size);
    return result;

(ucnv_toUChars fills array in second argument with UTF16 string and returns its size)

Is it safe to use return value of QString::utf16() this way in this context (QString is always created on stack locally)?

I don't use QString::fromUtf16 because I'd like to avoid data copying.
