Mirth Property File Corrupted on Editing using powershell - powershell

Question

I am trying to edit the Mirth property file to add microsoft sql server driver url and class name using powershell. I am able to edit and save . When I start the Mirth services after editing, the Mirth property file is corrupted. But I reviewed both the original and the edited content. Everything is the same except the added changes and the file size is increased from 5kb to 10 kb. Can anyone help me out? Here is the powershell script.
$server="Localhost"
$PropertyfilePath = "C:\Program Files\Mirth Connect\conf\mirth.properties"
$connectionString = "jdbc:sqlserver://$($server):1433;instanceName=$($server);databaseName=Mydb;integratedSecurity=true"
$driverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver"
$data= #()
Copy-Item $PropertyfilePath "D:\Mirthbackup" -force
$newstreamreader = New-Object System.IO.StreamReader($PropertyfilePath)
[int]$eachlinenumber = 1
while (($readeachline = $newstreamreader.ReadLine()) -ne $null)
{
if($readeachline.Contains("= derby")){
$readeachline.Remove(0)
$update= "database = sqlserver"
$data +=$update
$eachlinenumber++
}
elseif($readeachline.Contains("database.url"))
{
$update=$readeachline.Substring(0,12)+" = "+$connectionString
$data +=$update
$eachlinenumber++
}
elseif($readeachline.Contains(".driver"))
{
$readeachline.Remove(0)
$update ="database.driver = "+$driverName
$data +=$update
$eachlinenumber++
}
else{
$data +=$readeachline
$eachlinenumber++
}
}
$newstreamreader.Dispose()
$data | Out-File -FilePath $PropertyfilePath

Your properties file should be ISO-8859-1 (latin1) encoded.
Try to change your code to:
$server="Localhost"
$PropertyfilePath = "C:\Program Files\Mirth Connect\conf\mirth.properties"
$connectionString = "jdbc:sqlserver://$($server):1433;instanceName=$($server);databaseName=Mydb;integratedSecurity=true"
$driverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver"
$data= #()
Copy-Item $PropertyfilePath "D:\Mirthbackup" -force
$encoding = [System.Text.Encoding]::GetEncoding('iso-8859-1'))
$newstreamreader = New-Object System.IO.StreamReader($PropertyfilePath, $encoding)
[int]$eachlinenumber = 1
while (($readeachline = $newstreamreader.ReadLine()) -ne $null)
{
# if statements left out
}
$newstreamreader.Dispose()
[System.IO.File]::WriteAllLines($PropertyfilePath,$data, $encoding)
