      Work Description: SuJinpei commented on pull request #1850: [TRAFODION-3320] support multiple characters field and record separator when for data loading and extracting
URL: https://github.com/apache/trafodion/pull/1850
 
 
   **changes:**
   
   1. add two options: 'mcfs' and 'mcrs' to specify the multi-character field separator and record separator.
   2. add two functions: 'replace_escapes' and 'hextobin' to handle escape sequences in the separator.
   3. currentFiledPos -> currentFieldPos 
   
   **separator check algorithm:**
     check last few characters in temp field buffer to see if we found a field separator and record separator.

> we want to use "|@" as the field separator and "strX'A'B'C'" as the record separator, we can use below command:
> {code:bash}
> ./odb64luo -l src=td.data:tgt=tablename:mcfs="|@|":mcrs="strX'A'B'C'"
