Unprinted characters (also known as control characters) are characters that are interpreted as something other than a letter or character. These could be line or page breaks, or acknowledging the reception of data two or from a teletype. What characters are printing, non-printing, or unused depends on the software you are using, not Linux itself.
Linux does not have a limit as to the number of characters you can enter in a command.

Starting from /home, the path may include up to 4,091 additional characters (that is, Linux supports 4096 characters for the path, with up to 256 characters per file or directory name). This is a limitation of the kernel, and not of the file system. It is technically possible to modify the Linux kernel to support even longer file and path names if a user needed to do so.
