Luckily I could avoid it in the past 8 years :-)

I don't have a solution for your particular problem, but using the
Google JSON API and the JSON parser that comes with Seaside 3.0 this
works really well. I followed the instructions given here:
<http://stackoverflow.com/questions/1136604/how-do-i-use-the-json-google-translate-api>.

  url := WAUrl absolute:
'http://ajax.googleapis.com/ajax/services/language/translate?v=1.0&ie=UTF8'.
  url addParameter: 'langpair' value: 'de|en'.
  url addParameter: 'q' value: 'Wenn wir uns selbst fehlen, fehlt uns
doch alles.'.
  response := JSJsonParser parseStream: (HTTPSocket httpGet: url printString).
  ((response at: 'responseData') at: 'translatedText')

The above workspace code doesn't deal with encodings (that would have
to be fixed), but it basically works.

Cheers,
Lukas
