Removing invalid files
I wanted to remove the folder named 
'!Warning'$'\240' but it doesn't remove because Android thinks it cannot be found but it is there in Termux. How do I fix this?

Its probably RO or get dynamically written then deleted
This was a mirror of a FTP with stuff for the RiscPC where they had weird filenames
Now the backslash shouldn't be there
I could view files in a hex viewer but not remove it
Are you sure the FTP server is disabled before trying any operations?
Checking other tools helps to track down the problem but !Warning�
rm the dir
although a bit late, it's 
"!Warning"$'\240'. because 'a''b' will not concat unless 'b' is "b".
