EnumerateRemoteFiles and FileExists not working correcly for file with parenthesis in file name

I am using the EnumerateRemoteFiles and FileExists in a PowerShell script and it is not always working correctly for file with parenthesis () in file name especially when I add the a wildcard * to find many files.

PowerShell script: 
...
function fct_Open
{
   param 
   (
      [string]$OutLogPathFile
   )
 
   $sessionOptions = New-Object WinSCP.SessionOptions -Property @{

       UserName   = removed for security
       Password   = removed for security 
       HostName   = removed for security
   }
   
   $OutboundPathFile = $FolderLocalLog + '\' + $OutLogPathFile
   $session.SessionLogPath = $OutboundPathFile
   
   #The value can be -1 = Reduced, 0 = Normal, 1 = Debug 1 or 2 = Debug 2 logging levels
   $session.DebugLogLevel = 2
    
   # Connect
   $session.Open($sessionOptions)
}

Re: EnumerateRemoteFiles and FileExists not working correcly for file with parenthesis in file name

Please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate the session log file, set Session.SessionLogPath. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

I have included the log files

Hello Martin,
I thought I had included the WinSCP log files (in private mode) when I first created this Bug report but I have attached the log file document once again.

I have merged them all in one attachment. You will find them in the attach document: TestWindSCP2_WinSCPLogs_20230330.log

Re: I have included the log files

Indeed you did. I didn't notice before. Thanks.
I have added the issue with Session.EnumerateRemoteFiles to the tracker:
Issue 2177 – Session.EnumerateRemoteFiles does not work correctly when the mask includes brackets and other symbols

I'm sending you an email with a development version of WinSCP to the address you have used to register on this forum.
As for the Session.FileExists:
It does not allow wildcards:
