Danny Chen commented on FLINK-17631:
------------------------------------
I need to use the char config option for the CSV format, it has many char
delimiters config options.
Finally i use the string options first and do the validation by myself, but, as
a basic data type of Java, i think supports a char type seems more natural for
users.
