How do you remove specific special characters from a field value?

Hi, I have a field called "Employee_Email". This field contains the value:

["firstname.lastname@gmail.com"]

How do I remove the special characters [" and "]?

 

I tried: 

| eval test1 = replace (Employee_Email "[" , "")

 

But when I tried to remove either [ or " it gives me the following errors:

Error in 'EvalCommand': Regex: missing terminating ] for character class

Or:

Unbalanced quotes.

 

Is there a way to ignore the normal effect of [ and "?

You need to escape the square brackets and double quotes

| eval test1=replace(replace(Employee_Email,"\[\"",""),"\"\]","")

As an alternative you can use other functions

| eval trimmed_email=trim(Employee_Email,"\"[]")

or

| eval substr_email=substr(Employee_Email,3,len(Employee_Email)-4)
