Please comment on below piece of code :-

static void normalizeSpaces(String& text)
{
    unsigned textLength = text.length();

    unsigned i = 0;
    for (; i != textLength; ++i) {
        if (spaceNeedsReplacing(text[i]))
            break;
    }

    if (i == textLength)
        return;

    WTF::Vector<UChar> charVector(textLength);
    memcpy(&charVector, &text, i * sizeof(UChar));
    charVector[i] = ' ';
    ++i;

    for (; i != textLength; ++i) {
        if (spaceNeedsReplacing(text[i]))
            charVector[i] = ' ';
        else
            charVector[i] = text[i];
    }

    text.adopt(charVector);
}
