Problem with compare two String in powershell

Question

I want to identify the type of web part by its name, in this case "news". If the title of the web part was the same as "string2" I would like to delete this web part. I don't understand why I keep getting false. I also tried compareTo.

If I write the value of the variable -> $webParts.Title

I get the string "Wiadmości" I do a comparison with the string "Wiadmości" I get false

$global:importFileName="sitesURL.csv"
functionmain()
{
$sites=import-csv$global:importFileName
$global:credentials=Get-Credential
ForEach($sitein$sites)
    {           
RemoveWebParts-sourceUrl$site.spUrl-location$pwd
    }
}
 
functionRemoveWebParts(){
Param( $sourceUrl
) Process{
Write-Host"###################### '$sourceUrl' ######################"-ForegroundColor Green
Connect-PnPOnline-Url$sourceUrl-Credentials$global:credentials
$page=Get-PnPClientSidePage-Identity"Home.aspx"

Write-Host"Search web parts:"-ForegroundColor Cyan
$webParts=$page.Controls

$loopCounter=0
foreach($webpartin$webparts) {
 
        [String] $string1=$webParts.Title
        [String] $string2="Wiadomości"

if( $string1-eq$string2) {
Remove-PnPClientSideComponent-Page$page-InstanceId$webpart.InstanceId
Write-Host"Deleted '$webpart.Title'"-ForegroundColor Green 
$loopCounter++
        }
    }
if($loopCounter-gt0){
Write-Host"Removed web parts '$loopCounter'"-ForegroundColor Green
    }
Write-Host"No items were found for removal "-ForegroundColor Yellow
}
}
Measure-Command {main}

Something is wrong with the code you pasted. It is missing alll spaces in each row. Can you re-paste the code, please? — Denis Molodtsov

It could be that the something is wrong with the accents or with casing. Or maybe there is some extra character in a string.

Always use single quotes when defining variables. Just in case there is a special character in your string:

[String] $string2='Wiadomości'

This is the best way to compare two strings:

[System.StringComparer]::InvariantCultureIgnoreCase.Compare($string1.trim(), $string2.trim())

There is a problem with the character encoding. The variable "Wiadomości" has a different number of bytes when printed than what I return from the web $webParts.Title. I am now retrieving the variables from a csv file and everything is fine.
