questions about IOHandler class in "in_tail.rb"

[Eugene Gwon]

Hello,

    I'm using Fluentd with Graylog. these combination works well, but unfortunately, Fluentd can't parsing Korean characters by default

after I modified IOHandler class in "in_tail.rb", then It parsing without error.

but I'm new to Fluentd and Ruby, so I'm not sure that my modification is correct...

Is it safe to use? 

thanks for any help :)

--------------------------------------------------------------------

here's the code :

(/opt/td-agent/embedded/lib/ruby/gems/2.1.0/gems/fluentd-0.12.20/lib/fluent/plugin/in_tail.rb)

class IOHandler
    def initialize(io, pe, log, read_lines_limit, first = true, &receive_lines)

         @log = log

         @log.info "following tail of #{io.path}" if first

         @io = io

         @pe = pe

         @read_lines_limit = read_lines_limit

         @receive_lines = receive_lines

         #Eugene modified for korean character convert error

         #@buffer = ''.force_encoding('ASCII-8BIT')

         #@iobuf = ''.force_encoding('ASCII-8BIT')

         @buffer = ''.force_encoding('UTF-8')
         @iobuf = ''.force_encoding('UTF-8')

   end

and here's the version of td-agent :

ii  td-agent        2.3.1-0    amd64     Treasure Agent: A data collector for Treasure Data

It seems safe for me.

But if your logs contain invalid charactor as a UTF-8,

in_tail will raise an error.
