Supporting more encodings through other modules

[Zirro]

There are some modules which provide support for encodings not implemented by iconv-lite. Do we want to use them as well in order to cover more of the required encodings?

• ISO-2022-JP: https://github.com/narirou/jconv
• ISO-8859-8-I: https://github.com/mathiasbynens/iso-8859-8-i
• x-mac-cyrillic*: https://github.com/mathiasbynens/x-mac-cyrillic

* I think iconv-lite might support this one under the alternative name maccyrillic, which we ought to look into first.

Yes, that'd be great!
