I believe
read_nonblockusesread, which in turn says:Which means you don’t need to specify
IO#set_encoding, but that you can, after you read whole string, force its encoding (usingString#force_encoding!) toUTF-8.I emphasized ‘whole’, as you need to make sure that you read entire Unicode character at the end of the string, as if only part of it is read, you will get invalid UTF-8 character and Ruby might complain about it further down the line.
