The "wchar" encoding isn't really an encoding -- it's what we internally use as the representation of decoded characters. In practice, it tends to behave a lot like the 8bit encoding when used from userland, because input code units end up being treated as code points. This patch removes the wchar encoding from the public encoding list and reserves it for internal use only.
