BBC BASIC (when running on Windows) doesn't support Unicode filenames (or pathnames) - this is because Windows uses UTF-16 when all the other supported platforms use UTF-8.
Yes, a Windows problem and with no clear error message it tooks me a little while to find the problem. Thank you for your message, it's solved now, and for the IDE too, obviously it refused to work at first... :) Thank you for BBCSDL, it's something great. King regards. Cédric
I have rebuilt the Forces of Darkness executable so that it will run successfully from (for example) the Téléchargements directory, I will upload it to Itch in the near future. Making the BBCSDL IDE run is more difficult!
