The message sent by the writer is "hello" - it only contains ASCII characters, so any of US-ASCII, UTF-8, or ISO-8859-1, which are all compatible with ASCII (meaning: all these encode ASCII chars in the same way) would work.
In fact any charset in which "hello" is mappable would work. We simply need to make sure to use the *same charset* when encoding or decoding.
