Sometimes, that might still make sense, as for control characters, non-breaking space, etc. But for strings that is supposed to be a coherent text in a language that needs non-ASCII parts of Unicode, this is not so. Instead, having the sequences makes the text just harder to read and edit. We have already removed several such sequences before, but some remains.

Those TimeZoneNames* resource bundles are in fact leftovers from COMPAT locale provider removal. I am going to remove those files later so you can exclude them.
