Great! thanks Allin!
It is not a major problem but I have this every year with my students.​

Ok, exam grades turned in so here we go. I've replicated your set-up on Windows 10, running in English but trying to access a data file inside a Desktop subdirectory named "test" in Greek letters (that is, tau-epsilon-sigma-tau).

There are at least three ways to open a data file or script file that's suitably associated with gretl:

1) In the native file manager, double-click on the file: this should send a directive to the operating system to launch gretl with the given filename as a command-line argument.

2) Start gretl, then locate and select the file via the native file manager, and drag the file onto the main gretl window.

​Did not try this​ before. I tried it now and I got this:

3) Start gretl then use its menus (e.g. /File/Open data/User file...) to launch the GTK File dialog, select the desired file, then click the "Open" button (or double-click).

​In the second I sent you I did this.

(Once a file has been successfully opened there's a fourth way; that is. re-select the file under the menu of recently-opened files.)

So here's what I've found: methods 2 and 3 work fine to open a file within a Greek-named directory, but method 1 fails as you showed, with the puzzling error message in which the filename is shown with the Greek-letter sequence tau-epsilon-sigma-tau replaced by "test" (in Roman letters).

So it seems that when method 1 is used "somebody" is mistakenly transliterating the folder name before it gets to gretl. It could be Windows or it could be GTK (the cross-platform GUI tollkit that gretl uses). I've lodged a query with the GTK guys to try to determine if GTK might be messing with the filename before it reaches gretl.
