I have a file called `tst.csv` with the below content

```
"FORESS INTL PTN "A" (208)"

```

Need to get the below output and the requirement is we should not be using any escape character (`\`) and also `gsub`/`sub` only needs to be used to achieve the below expected output - as external program that we are using is not be decode the backslash character.

Expected o/p

```
"FORESS INTL PTN ""A"" (208)"

```

Tried the below command 

```
awk '{gsub(/"/,"&&");gsub(/^""|""$/,"")}1' tst.csv

```

I get the below o/p 

```
FORESS INTL PTN ""A"" (208)

```

But not able to get double quotes in front of the text nor at the end of the line.
