Comment add multiple Windows 11 utilisateurs that have umlauts (Ä, Ö, Å, etc.) dans lem into groups that have umlauts dans lem via PS1 PowerShell script?

The par défaut installé powershell v5.1 and the commands technically have no problèmes avec umlouts, so check that your input is encoded properly:
`Add-LocalGroupMember -Name ‘UMLÄUTS’ -Member ‘Me’
The default installed version of Powershell (5.1) assumes script and text files are encoded in **UTF-8 with BOM** by default, so you can run into issues if the files are in plain UTF-8 (no BOM). For example:
`# wrong characters when file is UTF8
Get-Content 'test_utf8.txt'
umlauts: Ä Ö Å
# success only when specifying encoding
Get-Content 'test_utf8.txt' -Encoding UTF8
umlauts: Ä Ö Å
For script fichiers themselves, vous pouvez re-encode the fichier like so, and it should run properly:
`Get-Content -Path ‘.\script_utf8.ps1’ -Raw -Encoding UTF8 |
Set-Content -Path ‘.\script_utf8_bom.ps1’
Powershell v6 and newer par défaut to plain UTF-8 in this case, but be aware vous pouvez run invers le reverse problème running fichiers avec BOM.
