Hi Team, 
 I am getting special character i.e ";" in empty field, how to remove the special character and save the value?

Yeah, need more info and Stewart is (obviously) right on and you need to rethink your code. 
 I'm not sure why you're displaying an array in a single text field both the below code can work depending on your exact use case. 
 a!localVariables(
 local!myArray: {"",""},
 local!emptyIndexes: where(
 a!forEach(
 items: local!myArray,
 expression: a!isNullOrEmpty(fv!item)
 )
 ),
 {
 a!textField(
 label: "Concatenate your array",
 value: concat(local!myArray)
 ),
 a!textField(
 label: "Remove empty indexes",
 value: remove(
 local!myArray,
 local!emptyIndexes
 )
 )
 }
)
