The below one will fail in a script, both both work from the PowerShell prompt:
Success
Get-NetFirewallRule -DisplayGroup "File and Printer Sharing" | ForEach-Object { Write-Host $_.DisplayName ; Get-NetFirewallAddressFilter -AssociatedNetFirewallRule $_ }
Failure
Get-NetFirewallRule –DisplayGroup "File and Printer Sharing" | ForEach-Object { Write-Host $_.DisplayName ; Get-NetFirewallAddressFilter -AssociatedNetFirewallRule $_ }
The error you get this this:
At C:\bin\Show-File-and-Printer-Sharing-firewall-rules.ps1:5 char:52
+ ... -TCP-NoScope" | ForEach-Object { Write-Host $_.DisplayName ; Get-NetF ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The string is missing the terminator: ".
+ CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : TerminatorExpectedAtEndOfString
Via [WayBack] script file ‘The string is missing the terminator: “.’ – Google Search, I quickly found these that stood out:
Cause and solution
Before DisplayGroup, the first line has a minus sign and the second an en-dash. You can see this via [WayBack] What Unicode character is this ?.
Apparently, when using Unicode on the console, it does not matter if you have a minus sign (-), en-dash (–), em-dash (—) or horizontal bar (―) as dash character. You can see this in [WayBack] tokenizer.cs at function [WayBack] NextToken and [WayBack] CharTraits.cs at function [WayBack] IsChar).
When saving to a non-Unicode file, it does matter, even though it does not display as garbage in the error message.
Similarly, PowerShell has support for these special characters:
internal static class SpecialChars
{
// Uncommon whitespace
internal const char NoBreakSpace = (char)0x00a0;
internal const char NextLine = (char)0x0085;
// Special dashes
internal const char EnDash = (char)0x2013;
internal const char EmDash = (char)0x2014;
internal const char HorizontalBar = (char)0x2015;
// Special quotes
internal const char QuoteSingleLeft = (char)0x2018; // left single quotation mark
internal const char QuoteSingleRight = (char)0x2019; // right single quotation mark
internal const char QuoteSingleBase = (char)0x201a; // single low-9 quotation mark
internal const char QuoteReversed = (char)0x201b; // single high-reversed-9 quotation mark
internal const char QuoteDoubleLeft = (char)0x201c; // left double quotation mark
internal const char QuoteDoubleRight = (char)0x201d; // right double quotation mark
internal const char QuoteLowDoubleLeft = (char)0x201E; // low double left quote used in german.
}
The easiest solution is to use minus signs everywhere.
Another solution is to save files as Unicode UTF-8 encoding (preferred) or UTF-16 encoding (which I dislike).
