Description
The following converters: Cp1381, Cp1383, Cp970 and Cp33722 contain 
char->byte mappings which appear to be no longer valid and which
have the potential to cause round-trip mapping errors.
These need to be examined in the context of cleaning up existing 
converters or within the migration to the NIO based charset API
of the various non platform converters.

The specific mappings which need to be removed are:

For Cp1381  U+7AC2 -> \xA1\xA4
For Cp1383  U+50FF -> \x1A
For Cp33722 U+551E -> \xC0\xE6
For Cp970   U+25C9 -> \xA2\xC1
