Hello, i have the following code but the value from title in AD has a (-) it but outputs a (?) in the CSV file

Import-Module ActiveDirectory
$File = Import-Csv "c:\scripts\ceridian\05-22-2013_CeridianExport.csv"
$AD = Get-ADUser -SearchBase "OU=OU,DC=DOMAIN,DC=COM" -filter * -Properties sAMAccountName,sn,givenName,title,employeeNumber | Where { $_.DistinguishedName -notmatch "OU=VIP" -and $_.DistinguishedName -notmatch "OU=DA"} | Select-Object  sAMAccountName,sn,givenName,title,employeeNumber
$ADMisMatch = @()
Foreach ($AD_User in $AD){
If (!($File | ?{$AD_User.EmployeeNumber -eq $_."Clock Number" -and $AD_User.sn -eq $_."Last Name" -and $AD_User.givenName -eq $_."First Name" -and $AD_User.title -eq $_."Job Title"}))
    {
        $ADMisMatch += $AD_User
    }
}
$ADMisMatch | Sort-Object -Property "sn", "givenName" | Select sn,givenName,title,employeeNumber | Export-Csv "c:\scripts\ceridian\05-23-2013_ADMisMatch.csv" -NoTypeInformation

Title in AD:Manager – Systems/Network
title in CSV file:Manager ? Systems/Network

Thoughts ?
