   doris version: 0.14
   flink-doris-connector version : master
   flink version : 1.12.2
   
   When we repalce `column_separator=%x01 ` and `line_delimiter=%x02`, have 
other error occurs :
   ```bash
   Reason: actual column number is more than schema column number. actual 
number: 1900 sep: %, schema number: 19; . src line: 
[689%x018a7c7089faaf00c850b90154e74fb821%x01101787%x0111%x010%x010%x010%x01%x01%x01QARFEE
 
   ```
   We check barch-0.14 and master, look the commit message `[Load] Support 
multi bytes LineDelimiter and ColumnSeparator` (#5462) in  
`broker_scanner.cpp`, so we are going to verify it.
