@T1092:R Added support for long char whose length is more than 255 bytes...

....  This happens if the column's character encoding is set to UTF8 and the column length is set to 86 or more (86 * 3 = 258)

Tested with the following table.  Column "test" is a long char column which uses 2 byte for string length.  Column "smallchar" is a regular char column which uses 1 byte for string length.

With this fix, an insert record looks like this.  Note that the values have been set correctly.
```
{"row":{"1":"g1","2":"g2","3":"0SL00000007"},"type":"insert","respect_order":true,"table_name":"chartest","src_pos":"mysql-bin-changelog.000582\t249","table_rev":2,"seq":9}
