How can I use accented characters in the echo command in Batch?

Question

Hello people of Stack Overflow. Me and my friend are making a game in the Batch/.bat programming language. Up until this point, we have had no problems that we couldnt fix. When

Answer 1

Use in batch file

SETLOCAL EnableDelayedExpansion

@CHCP 65001 >NUL

Answer 2

• Save the batch file in UTF-8 without BOM signature and use UTF-8 codepage:

  chcp 65001 >nul
  echo Päivää Привет Hello
  

• Or make a file with messages for each language and save it in unicode encoding (UTF-16LE):

  en.hello=Hello
  .......other messages
  fi.hello=Päivää
  .......other messages
  

  Then load the translations:

  set LANGUAGE=fi
  ...............
  for /f "tokens=1* delims=." %%a in ('type "%~dp0messages.txt') do (
      if "%%a"=="%LANGUAGE%" set "msg.%%b"
  )
  ...............
  echo %msg.hello%
  

  Now the messages should be displayed correctly by default since the system console codepage usually corresponds to the language set in regional settings.

  Päivää

  You can keep these messages in readable form inside the batch file saved as UTF-8 without BOM signature and use an embedded VBScript/powershell code to extract to messages.txt in UTF16-LE encoding:

  ::msg.en.hello=Hello
  ::msg.fi.hello=Päivää
  powershell -c "Get-Content '%~f0' -encoding UTF8 | Select-String -Pattern '^::msg\.' | ForEach-Object {$_ -replace '::msg.',''} | Set-Content '%temp%\messages.txt' -encoding Unicode"
  

  And then load it as shown above.
