File path encoding issue in GfxProcessor::readBitmap on Windows

[zenden2k]

I created a custom GFX processor class derived from MegaGfxProcessor.
MEGA SDK documentation doesn't mention this but const char* path parameter in function MegaGfxProcessor::readBitmap contains a pointer to UTF-16 encoded string (which is odd) on Windows.
I cannot use this string as wide-char string because it is not null-terminated in UTF-16 sense (
it should contain two zero bytes at the end), so I cannot determine it's length.

bool MyGfxProcessor::readBitmap(const char* path) {
    CString widePath = reinterpret_cast<const wchar_t*>(path);
