Manu Kaul commented on FLINK-1168:
----------------------------------

I am starting to look at this issue. Can I please get some more background on 
this issue? 
1. Why does the CSV file need a "multi-char field delimiter"? For example a 
line like :  "123,45", 45, "abc", 33 ... should still parse. 
2. Is there a restriction we should enforce on the set of characters that 
should be allowed in such a delimiter? 

The only reason I am seeing for a multi-char field delimiter is when the single 
char delimiter like "," or "|" ends up being in the content of the actual field 
contents. Is that right?
