                                                                                  I am using the FSharp.Data for downloading and parsing an XML document. The document contains several nordic characters, like: "Lempäälän Keskus". I have a simple code like this:

                                                                                  open FSharp.Data
                                                                                  open System.IO
                                                                                  
                                                                                  let xml = Http.RequestString(downloadUrl)
                                                                                  File.WriteAllText("response.xml", xml)
                                                                                  

                                                                                  However, when I open the resulting file, the characters are corrupted and I see this: "Lempäälän Keskus". I have tried manually re-saving the file with the ISO-8859-1 encoding and then reopening with UTF-8 (in VS Code). This fixed the displayed text. Then tried to implement a simple encoding conversion function:

                                                                                  open FSharp.Data
                                                                                  open System
                                                                                  open System.IO
                                                                                  
                                                                                  let convertEncoding (input: string) =
                                                                                    let iso = Encoding.GetEncoding("ISO-8859-1")
                                                                                    let utf8 = Encoding.UTF8
                                                                                    let isoBytes = iso.GetBytes(input)

                                                                                    utf8.GetString(utfBytes)

                                                                                  However, when I open the file, I still see "Lempäälän Keskus" instead of "Lempäälän Keskus". What am I doing wrong?
