Issue #20069 has been updated by ioquatix (Samuel Williams).
ruby use String to deal with bytes, this cause error on irb "invalid byte sequence in utf-8"
This is desirable behaviour. The String with UTF-8 encoding cannot contain invalid byte sequences. If you want to store binary data, use `Encoding::BINARY` encoding.
can we get a builtin class like Buffer or Bytes that represent as hex string
A Binary string already presents the inspect output as a hex encoded String. As others have pointed out, if you want actual memory mapped binary buffers, use `IO::Buffer`. ---------------------------------------- Feature #20069: Buffer class in stdlib https://bugs.ruby-lang.org/issues/20069#change-105755 * Author: pynix (Pynix wang) * Status: Open * Priority: Normal ---------------------------------------- ruby use `String` to deal with bytes, this cause error on irb "invalid byte sequence in utf-8" can we get a builtin class like Buffer or Bytes that represent as hex string -- https://bugs.ruby-lang.org/
