No. `wchar_t` normally does not use multi-wchar_t encoding, at least within the tested range.

Well, that's what I suspected. I presume that it worked with the previous version just fine. Therefore, we have different implementations making different assumptions as to what to do with `\xDA`.
I don't think killing the whole test on some implementations like we're doing right now makes sense. Either we should stop testing the 'undefined behavior', or maybe allow for both values.
