Hash a string in Powershell with various encryption algorithms

Powershell_String_Hashes.ps1

#Here is a simple script to hash a string using your chosen cryptography algorithm.
#Usage Examples:
#Get-StringHash "My String to hash" "MD5"
#Get-StringHash "My String to hash" "RIPEMD160"
#Get-StringHash "My String to hash" "SHA1"
#Get-StringHash "My String to hash" "SHA256"
#Get-StringHash "My String to hash" "SHA384"
#Get-StringHash "My String to hash" "SHA512"

Function Get-StringHash([String] $String,$HashName = "MD5")
{
$StringBuilder = New-Object System.Text.StringBuilder
[System.Security.Cryptography.HashAlgorithm]::Create($HashName).ComputeHash([System.Text.Encoding]::UTF8.GetBytes($String))|%{
[Void]$StringBuilder.Append($_.ToString("x2"))
}
$StringBuilder.ToString()
}

$myvar = Read-Host –Prompt 'Enter string to hash using SHA-512 algorithm'
Get-StringHash $myvar "SHA512"
Write-Host "Press any key to continue ..."
$x = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")

#PowerShell #encryption

$myvar = Read-Host –Prompt 'Enter string to hash using SHA-512 algorithm'$myvar

The dash before "Prompt" is an endash, script doesn't run. I get

At C:\Users\Nope\Powershell_String_Hashes.ps1:25 char:51
+ $x = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")
+                                                   ~~
The string is missing the terminator: ".

    + FullyQualifiedErrorId : TerminatorExpectedAtEndOfString

Easy enough to fix in the editor, but figured you might want to know that, might be some weird encoding bug that the character was replaced at some point.
