I get in some translations from google-translate api

Question

I am new to using the Google translate API, and during testing we noticed that for some translations (I couldn’t find a template yet) we get characters in the response. This leads to many problems, and, above all, it does not seem like any purpose or meaning. As a simple example:

https://www.googleapis.com/language/translate/v2?key=YOURKEY&source=NL&target=EN&q=Hergeneer%20verkopen

returns:

{
 "data": {
  "translations": [
   {
    "translatedText": "Sell \u200b\u200bHerge Down"
   }
  ]
 }
}

Our software stumbles upon these lines / characters, and I have not found a way to prevent them or get rid of them.

Can anyone shed some light?

Thank,

-Peter
