> Hi,
> If we have a dataframe with the column value as {noformat} ab\,cd\,ef\,gh {noformat}
> Then while writing it is being written as 
> {noformat} "ab\,cd\\,ef\\,gh" {noformat}
> i.e it double escapes all the already escaped commas/delimiters but not the first one.
> This is weird behaviour considering either it should do for all or none.
> If I do mention df.option("escape","") as empty then it solves this problem but the double quotes inside the same value if any are preceded by a special char i.e '\u00'. Why does it do so when the escape character is set as ""(empty)?
