Vikash Talanki updated PHOENIX-3187:
------------------------------------
Description:
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.
