Add or remove text from text file using PowerShell - powershell

Question

I'm using PowerShell to add or remove text from file. I'm keep getting funny text in my file.
This only happens when I have removed the line from the text file and when I try to add new line I get funny text.
cls
IMPORT-MODULE ActiveDirectory
$fileLocation = "E:\Script\MatchCadTest\ptc.opt";
function addUser( $username=''){
$user = Get-ADUser -Identity $username -ErrorAction SilentlyContinue;
$userFullName = $user.Name;
$empty = [string]::IsNullOrEmpty($userFullName);
if ( !($empty) ){
$userExisted = Get-Content $fileLocation | Select-String "$username" -quiet
if( ! $userExisted ){
$newLocation = "E:\Script\MatchCadTest\backup\";
if((Test-Path -Path $fileLocation)) {
Copy-Item "$fileLocation" "$newLocation"
}
$date = Get-Date -Format "d-M-y Hms";
$newName = "ptc_$date.opt"
Rename-Item "$newLocation\ptc.opt" $newName
# Add-Content $fileLocation ""
Add-Content -Path $fileLocation -Value "# $userFullName";
Add-Content -Path $fileLocation -Value "INCLUDE MATHCAD USER $username";
Write-Host "User has been added to file. Please restart the service." -BackgroundColor Green -ForegroundColor Black
}
else{
Write-Host "User already existed" -BackgroundColor Red -ForegroundColor White
}
}
}
function removeUser( $username=''){
$user = Get-ADUser -Identity $username -ErrorAction SilentlyContinue;
# $user
$userFullName = $user.Name;
$empty = [string]::IsNullOrEmpty($userFullName);
if ( !($empty) ){
$userExisted = Get-Content $fileLocation | Select-String "$username" -quiet
if( $userExisted ){
$remove="# $userFullName";
$removeUser = (Get-Content $fileLocation);
$removeUser | where {$_ -ne $remove};
$remove="INCLUDE MATHCAD USER $username";
$removeUser | where {$_ -ne $remove}
$removeUser |Out-File $fileLocation;
#$removeUser = (Get-Content $fileLocation) | where {$_ -ne $remove} | Out-File $fileLocation;
#$content = Get-Content $fileLocation
#$content | Foreach {$_.TrimEnd()} | Set-Content $fileLocation
Write-Host "User removed" -BackgroundColor Green -ForegroundColor Black
}
else{
Write-Host "User does not existed" -BackgroundColor Red -ForegroundColor White
}
}
else{
Write-Host "User not found in ad" -BackgroundColor Red -ForegroundColor White
}
}
$option=''
while ( $option -ne 0){
Write-Host "What would you like to do?"
Write-Host "1= Add new user"
Write-Host "2= Remove user"
Write-Host "0= No (Exit)"
$option = Read-Host "Select option"
$username = Read-Host "Please enter Username"
if( $option -eq 0 ){
exit 1
}
elseif( $option -eq 1){
addUser($username);
}
elseif ( $option -eq 22){
removeUser ($username);
}
else{
cls
Write-Host
Write-Host " Invaild Choice " -BackgroundColor Red #-ForegroundColor White
Write-Host
}
#Reset
$option=444;
$username="";
$userFullName="";
$user="";
$empty="";
}
When I remove the line of text from file and add a new user, it's all a funny text string:
See below
‣潍慨浭摡䴠橡摩਍义䱃䑕⁅䅍䡔䅃⁄单剅洠ㅭ㘳㐰ല
I have a text file with following information.
- // Full name 1
- User ID of User 1
- // Full name 2
- User ID of User 2
* // Full name 3
* User ID of User 3
* // Full name 4
* User ID of User 4
* // Full name 5
* User ID of User 5
* // Full name 6
* User ID of User 6
* // Full name 7
* User ID of User 7
* // Full name 8
* User ID of User 8
If you see that user 5 and 6 or 7 and 8 has extra space which i wont to remove and ad just sinlge space.

I think you need to set the encoding for your Add-Content
Try: Add-Content -Encoding UTF8 -Path $fileLocation -Value "# $userFullName";
