This is false. ISO/IEC 2022 is designed to allow mixing different encodings (including ASCII), and it is a common practice to mix in a Japanese string (or any of your choice) enclosed in a pair of "ESC $ B" (note: 'B' is for Japanese, but other character encoding can be specified in the same string by using a different letter here) and "ESC ( B" to go back to ASCII. So if you throw "remote: " at the beginning, that comes out in ASCII. The payload may have ISO/IEC 2022 encoded "foreign" letters, but again, they are closed with "ESC ( B" to switch back to ASCII, if you add random junk (like "..." perhaps) after them in ASCII, your random junk will come out in ASCII just fine.
