update-mguser encoding issues with displayname

[halukpn]

Describe the bug

I am trying to use the command:
Update-MgUser -UserID $id -DisplayName ""
To set display name for users. The displayname text is not encoded correctly.
For example:
Update-MgUser -UserID $id -DisplayName "11 & 22"
Display name ends up as: 11 u0026 22
And so on for other characters.
Also:
Update-MgUser -UserID $id -DisplayName "Ernst"
ends up as: Est (for some reason rn next to each other are always removed from a string)

I've tried escaping, quotes etc and nothing helps.

PowerShell 7.5 on Windows, in vscode or Windows terminal, same issue.

Expected behavior

Should be able to handle normal characters.

How to reproduce

Update-MgUser -UserID $id -DisplayName "11 & 22"
Update-MgUser -UserID $id -DisplayName "Ernst
