Answer 1

@peterSO has correct answer. I am adding more examples here:

package main

import (
    "fmt"
    strings "strings"
)

func main() { 
    test := "\t pdftk 2.0.2  \n"
    result := strings.TrimSpace(test)
    fmt.Printf("Length of %q is %d\n", test, len(test))
    fmt.Printf("Length of %q is %d\n\n", result, len(result))

    test = "\n\r pdftk 2.0.2 \n\r"
    result = strings.TrimSpace(test)
    fmt.Printf("Length of %q is %d\n", test, len(test))
    fmt.Printf("Length of %q is %d\n\n", result, len(result))

    test = "\n\r\n\r pdftk 2.0.2 \n\r\n\r"
    result = strings.TrimSpace(test)
    fmt.Printf("Length of %q is %d\n", test, len(test))
    fmt.Printf("Length of %q is %d\n\n", result, len(result))

    test = "\r pdftk 2.0.2 \r"
    result = strings.TrimSpace(test)
    fmt.Printf("Length of %q is %d\n", test, len(test))
    fmt.Printf("Length of %q is %d\n\n", result, len(result))   
}

You can find this in Go lang playground too.
