Bypass EUC and ISO-2022 encoding tables for iOS

It is questionable whether they are needed for any document
format. Saves 0.4 MB of app executable size. If it turns out that some
document format that support is needed for actually does need these
tables, will have to revert this then. An alternative, but more
complex, way to save executable size would be to put this, and other,
conversion data into a data file instead.
