"[SOLVED]questions of reading csv files"

When using “read csv” operator to import csv file, I have the following problem.

If a given cell has a “,”, the word following it will not be read.  I think this is because the “,” is used as the column operator. But for this case, “,” is just an character appeared in a string . How can I let rapidminer skip this “,” in the string.

The following is the test csv file, which just include one row with two columns. The main content is just a text string. in the gnerated wordlist, we can find that the word "what" was not read due to the "," appearing before it.

The following is the process
