• “Unknown escape sequence” error in Go 2 answers

I have an incoming string that looks like this

data-url==\"\/entity\/id\/2439918080\"

If I Println on this string, it throws an error unknown escape sequence: /

See http://play.golang.org/p/IbURcPc_gZ (comment the first statement and it works)

However if I replace \/ with \u002F it prints perfectly. The actual incoming data is full of such encoded urls. Is there anyway I can print it without having to change it to \u002F ?

Here is the actual string that comes from json

  <div class="card2 media-container portrait" data-card2-name="summary_large_image">
    
    <div class="js-macaw-cards-iframe-container"
  data-src="\/i\/entity\/tfw\/v1\/3298718080?cardname=summary_large_image&earned=true"
  data-autoplay-src="\/i\/cards\/tfw\/v1\/632987845439918080?cardname=summary_large_image&earned=true"
  data-card-name="summary_large_image"
  data-card-url="http:\/\/t.co\/QqWvUQMs5B"
  data-publisher-id="6721522"
  data-creator-id=""

If you are just trying to get a valid string :

package main

import "fmt"
import("strings")

func main() {

    s := `data-url==\"\/entity\/id\/2439918080\"`
    s = strings.Replace(s,"\\","",-1)
    println(s)

    //Replace \/ with \u002F works fine
    fmt.Println("data-url==\"\u002Fentity\u002Fid\u002F2439918080\"")
}
