File.lines.iterator() terminates the line where a colon is in a cell value in the csv file

Hello,

The iterator seems to be terminating the line where there's a colon in the cell value in the line, then it continues creating a new line where the it left off after the colon:

let iterator = csvFile.lines.iterator();

iterator.each(function(line) {

// the line shows that it ends where there's a colon in one of the csv cells

}

csv example: John,Doe,Netsuite Admin,"Skills: develop, workflows, saved searches",7/25/2018

after first run through each function line: {"John,Doe,Netsuite Admin,\"Skills:"}

after second run through each func line: {"develop, workflows, saved searches\",7/25/2018"}

QUESTION:

How to I prevent it from ending the line where there's a colon?
