If you want to find if the content is equal, regardless of characters position, you could break the string to its characters, sort the result and then use the Compare-Object cmdlet. No result means the variables are equal:
$v1 = $Var1.GetEnumerator() | Sort-Object {"$_"}
$v2 = $Var2.GetEnumerator() | Sort-Object {"$_"}
compare $v1 $v2
