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.

@magicus The ones under java.xml and jdk.jdi are updated by the translation team, I think it'd be best to remove those files from this change.
