QUESTION
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)
let utfBytes = Encoding.Convert(iso, utf8, isoBytes)
utf8.GetString(utfBytes)
let xml = Http.RequestString(downloadUrl)
let decoded = convertEncoding xml
File.WriteAllText("response.xml", decoded)
However, when I open the file, I still see "Lempäälän Keskus" instead of "Lempäälän Keskus". What am I doing wrong?
ANSWER
Answered 2021-Jan-15 at 15:08Provide encoding when you write text to file
let encoding = Encoding.GetEncoding("ISO-8859-1")
File.WriteAllText("response.xml", xml, encoding)

Install LEMPA
Download the software and extract it
Install avrdude if needed sudo apt-get install avrdude
Install prequisites: sudo apt-get install libopenjp2-7 and sudo apt-get install libtiff5
Install required libraries pip3 install -r requirements.txt
Make sure profiles.json reflects your environment
python3 program.py or python3 program.py <profile id>
Make sure you enable RPi interfaces: SPI, I2C, and Serial
id Unique ID for the profile
type bin or composite. Composite allows for multiple profile programming, one after another.
jumper optional If specified, and the relevant profile is chosen with a physical jumper, this profile will be used if none was specified as part of command line parameter.
device Type of device to program. Not required for ESP. See AVRDude for list of devices
autodetect If set to true, system will start programming as soon as it detects chip (does not work ESP)
bins List of bins to upload. For ATMega only one bin is required. For ESP multiple bins can be specified to support SPIFFS Bin method can be one of the following:
plugins System support a simple web server with the ability to send data to the ATMega via serial. This allows for parameter tweaking and QA.
