### Question:
UnicodeCodec extends CodecImpl { @NonNull @Override public String encode(@NonNull String text) { setMax(1); setConfident(0); try { String result = StringEscapeUtils.escapeJava(text); incConfident(); return result; } catch (Exception e) { return text; } }  @NonNull @Override String getName(Context context); @NonNull @Override String decode(@NonNull String text); @NonNull @Override String encode(@NonNull String text);  }### Answer:
@Test public void encode() throws Exception { String result = codec.encode(toBeEncode); assertEquals(result, toBeDecode); }
@Test public void encode_error() throws Exception { String result = codec.encode(Character.toString((char) 1)); assertEquals(result, "\\u0001"); }
