  Hi, i'm using Nim a week and stil cannot find the way to work with json in utf8. I have this:

  let json_resp = query.getContent()
  echo json_resp
  let parsed = parseJson(json_resp)
  echo parsed
  Run

  I have also imported unicode, strutils and json modules. And this is output:

  {"status":1,"status_message":"Не указан уникальный идентификатор мероприятия"}
  {"status":1,"status_message":"\u041D\u0435 \u0443\u043A\u0430\u0437\u0430\u043D \u0443\u043D\u0438\u043A\u0430\u043B\u044C\u043D\u044B\u0439 \u0438\u0434\u0435\u043D\u0442\u0438\u0444\u0438\u043A\u0430\u0442\u043E\u0440 \u043C\u0435\u0440\u043E\u043F\u0440\u0438\u044F\u0442\u0438\u044F"}
  Run

  As you can see without using "parseJson" everything is ok with encoding. Also, the same trouble with using % operator(the same modules was imported):

  var s = "блаблабла"
  echo s
  echo (%s)
  Run

  And I get:

  
  блаблабла
  "\u0431\u043B\u0430\u0431\u043B\u0430\u0431\u043B\u0430"
  Run

  It seems I'm doing something wrong, but it's really unusual behaviour for me. I cann't find anything in modules description.

  Thank you

  This is quite normal. You are first printing a string, then a json node. When Nim prints a json node, it escapes characters outside the range \u0020 to \u007f. When printing a string, it just prints the raw characters and doesn't escape them.

  To get at the underlying representation of a string, use getStr on the json node. E.g.:

  echo getStr(%s)
  Run

  Then it can be correctly read by other applications?

  It depends on what you want to read. If you want your other applications to read json output, use $ or pretty; the \u escapes are the normal way to print non-ASCII characters in json. If you want to get at the string contents of a json element without the escapes, use getStr for that element.

  Thank you. I'll try read it from Java soon
