I've recently learned that in Linux, you can use emois in filenames. I died a ~~little~~ lot inside when I learned that.
On Linux file systems you can use any character except NULL, and / is a reserved character.
E.g. on ext-4 "All characters and character sequences permitted, except for NULL ('\0'), '/', and the special file names "." and ".." which are reserved for indicating (respectively) current and parent directories."
I once accidentally created a file with a newline character in it... it was pretty tricky to fix from command line.
Did you not just use tab? That's the usual method of dealing with weird characters in filenames that I've found
This was quite a while ago now, but I don't think my shell escaped the tab complete properly, I remember it just printing a literal newline and evaluating it as a second command. I think there was other unicode in there too, otherwise I would have just typed it out. I had to do something with null terminated output and piping it in to
mv, but I can't remember what exactly.Too bad when there's multiple files starting with and consisting mostly of e.g. kanji (when on a Latin keyboard).
With the right shell, you can just press tab multiple times to cycle through the possible completions.
