Yes, of course, you can read any byte sequence. As you have experienced, if you send the byte values 194 and 165, your Arduino reliably reads 194 and 165.
Now, you have to be aware that there are tons of incompatible character encodings that could all be called "extended ASCII". I do not know which one you have in mind. Maybe there is such an encodingsencoding where "\" has the code point 157. Nowadays, however, almost any modern computer system uses Unicode, and serializes the characters using UTF-8. The character "\" is serialized in UTF-8 as the pair of code unitsbytes 194 and 165.
If you want to use the Grbl protocol, send interrupts as "bytes"bytes, do not think about them as "characters".
