Hmmm... Or, if PSPad still built by Delphi 7, this can be ANSI-only ParamStr issue. To avoid it, you should get Unicode command line via GetCommandLineW() and then parse in manually with WideString-based functions.
When testing on surrogate-pair-named file, I had no problems with my program built by Delphi 6, but used GetCommandLineW function as I wrote above. -- <http://forum.pspad.com/read.php?2,67631,67647> PSPad freeware editor http://www.pspad.com
