Description:

A compoundEncoder uses two real encoders;
to encode:
    string -> decoder(encode) -> encoder -> result
to decode:
    string -> encoder -> decoder -> result

|e|

e := CompoundEncoder new.
e encoder:ISO8859_5 decoder:KOI8_R.
e decode:16rB0.  'CYRILLIC CAPITAL LETTER A; 16rB0 in 8859-5; 16rE1 in KOI8-R'.
e encode:16rE1.
