As mentioned by Mofi, you could use variables with delayed expansion to echo any content.
There are some more possible ways.
1) Disappearing quotes
for /F %%^" in ("""") do (
echo %%~"Hello^you
echo %%~"Line2 |&<>
)
This works as the %~"
will quote the rest of the line, but after expansion it will disappear
2) When you want to echo multiple lines you should read about the different variants of heredoc
3) The MagicEcho can display any content without escaping or doubling percent signs like
%magicEcho% "^!%path%<>" ^%!%<> ^
