To start out I will quickly go over the variable types. There are four variable types in batch script, two are treated as plain text, and thus not already escaped, the other two are already escaped.
When used with echo the escaped variables can hold any characters except possibly the exclamation mark! The exclamation mark! It is also worth noting that exclamation marks will either disappear or expand as variables inside of Parameters, Standard Environment Variables and For Variables, unless the variable has the right number of carets already in it four or more depending on the circumstance. Specifically for cmd. Examples: rem output the dir command to file, overwrite the file if it already exists.
Redirecting the Error Stream Thus far we have only been redirecting the standard output of commands, but some commands will output errors in a different way. Examples: rem only errors into "somefile. Of course this can still result in trailing spaces, but only if the text you output has them. Character Escapement The final catch that echo has for us is dealing with characters that have special meaning to the command processor.
