             Summary: Issue when LIKE expression contains Chinese characters on 
Key column
                 Key: PHOENIX-1334
                 URL: https://issues.apache.org/jira/browse/PHOENIX-1334
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.1
         Environment: jdk 1.8 linux
            Reporter: wuyang


When I use like expression in SELECT query. It works well when I put *Chinese* 
characters in LIKE expression on NONE PRIMARY KEY columns . BUT when I put them 
in LIKE expression on *PRIMARY KEY* , it occurs an Exception:‍

 select * from "test3" where PK like '中%';  ‍

the type of PRIMARY KEY and ‍NONE PRIMARY KEY columns are all ‍VARCHAR‍

In the relative source code:

{code}
byte[] b = VARCHAR.toBytes(object);‍
 if (b.length != ((String) object).length()) {
                throw new IllegalDataException("CHAR types may only contain 
single byte characters (" + object + ")");
}‍
{code}

actually, Chinese (or other non-Latin) characters will never meet the condition 
b.length == ((String) object).length() . Default encode method is UTF-8.‍
