> If string field of thrift object contains character 
> ＜ 
> encoded as "\uff1c then parser can't parse such object at all and fails with: 
> {code}
> java.lang.IllegalArgumentException: -228
> 	at java.lang.String.<init>(String.java:266)
> 	at org.apache.thrift.protocol.TJSONProtocol.readJSONString(TJSONProtocol.java:691)
> {code}
> Here the unit test to reproduce it:
> {code}
> @Test
>     public void readUnicode_uff1c() throws Exception {
>         String jsonEncodedEntity = "{\"1\":{\"str\":\"\\uff1c\"}}";
>         byte[] bytesEntity = jsonEncodedEntity.getBytes();
>         TMemoryBuffer memoryBuffer = new TMemoryBuffer(bytesEntity.length);
>         memoryBuffer.write(bytesEntity);
>         memoryBuffer.close();
>         TJSONProtocol protocol = new TJSONProtocol(memoryBuffer);
>         protocol.readStructBegin();
>         protocol.readFieldBegin();
>         assertEquals("＜", protocol.readString());
>     }
> {code}
