Does Data.Aeson parse JSON as UTF-8 and numbers as decimal? You know, in real world business applications we don't use float/double or ASCII.

Of course. It uses the Text [0] and Scientific [1] packages under the hood. The internal ADT representing JSON is actually very simple (as json is very simple itself):

  data Value
    = Object (HashMap Text Value)
    | Array (Vector Value)
    | String Text
    | Number Scientific
    | Bool Bool
    | Null
