[jira] [Created] (PHOENIX-3187) Support multi-byte characters for CHAR datatype

Vikash Talanki created PHOENIX-3187:
---------------------------------------

             Summary: Support multi-byte characters for CHAR datatype
                 Key: PHOENIX-3187
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3187
             Project: Phoenix
          Issue Type: Improvement
    Affects Versions: 4.7.0
            Reporter: Vikash Talanki
            Priority: Minor


Currently, Phoenix CHAR data type supports only single byte characters. We need support for multi byte characters in CHAR datatype.

Case 1: Support multi byte characters in CHAR data type like VARCHAR - CHAR(1) can take any multi-byte character.
Case 2: Support multi byte characters in CHAR data type only if it fits in defined length - CHAR(1) takes only single byte character but CHAR(n) can take one n-byte character. In other words, the total number of bytes of all characters should not exceed the defined length.
