When the compiler sees this, it sees " Hello "World"" as three things - a string " Hello ", the token World and an empty string, "". To get it to recognise the middle quotes as part of the string, as opposed to the end/start of the string, you need to escape them with the \ character (just like you use \n and the compiler recognizes you mean a newline, not the letter 'n'):

I'm not very familiar with the ssh command. When I tried to set a variable and then echo its value on a remote machine via ssh, I found a problem. For example,

uuencode
uuencode(n) encode/decoding a binary file uuencode(n)
NAME
uuencode - encode/decoding a binary file
SYNOPSIS
package require Tcl 8
package require uuencode ?1.0.1?
::uuencode::encode string
::uuencode::decode string
::uuencode::uuencode ?-name string? ?-mode octal? (-file filename | ?--? string)
::uuencode::uudecode (-file filename | ?--? string)
DESCRIPTION
This package provides a Tcl-only implementation of the uuencode(1) and uudecode(1) commands. This encoding packs binary data into printable
ASCII characters.
::uuencode::encode string
returns the uuencoded data. This will encode all the data passed in even if this is longer than the uuencode maximum line length. If
the number of input bytes is not a multiple of 3 then additional 0 bytes are added to pad the string.
::uuencode::decode string
Decodes the given encoded data. This will return any padding characters as well and it is the callers responsibility to deal with
handling the actual length of the encoded data. (see uuencode).
::uuencode::uuencode ?-name string? ?-mode octal? (-file filename | ?--? string)
::uuencode::uudecode (-file filename | ?--? string)
UUDecode a file or block of data. A file may contain more than one embedded file so the result is a list where each element is a
three element list of filename, mode value and data.
OPTIONS -filename name
Cause the uuencode or uudecode commands to read their data from the named file rather that taking a string parameter.
-name string
The uuencoded data header line contains the suggested file name to be used when unpacking the data. Use this option to change this
from the default of "data.dat".
-mode octal
The uuencoded data header line contains a suggested permissions bit pattern expressed as an octal string. To change the default of
0644 you can set this option. For instance, 0755 would be suitable for an executable. See chmod(1).
EXAMPLES
% set d [uuencode::encode "Hello World!"]
2&5L;&@5V]R;&0A
% uuencode::uudecode $d
Hello World!
% set d [uuencode::uuencode -name hello.txt "Hello World"]
begin 644 hello.txt
+2&5L;&@5V]R;&0`
`
end
% uuencode::uudecode $d
{hello.txt 644 {Hello World}}
