Special character at beginning of the row

[Karuetl]

In a file each value is comma separated with enclosed double quotes , i got error when one of the row has special characters , how do i remove it

usually in the string we can use this function it may work 

row1.contains("?")? row1.replace("?","")

And question from my end is it at the start of the line in the file
