To reproduce:
- Create two blank files, e.g., C:\A.lua, and C:\Ø.lua.
- Script → Run Script… → C:\A.lua (no result)
- Script → Run Script… → C:\Ø.lua (console reads: “cannot open C:\Ø.lua: No such file or directory”)
This occurs for any Norwegian character (æÆøØåÅ), including if any parent directory contains any of them.
