Subject: [ruby-core:94361] [Ruby master Bug#6436] Byte counting incorrect in BufferedIO (net/protocol.rb)

Issue #6436 has been updated by jeremyevans0 (Jeremy Evans).

Status changed from Assigned to Closed

It looks like this issue was fixed between Ruby 2.4 and 2.5:

```
$ ruby24 -rnet/http -e "p Net::HTTP.start('www.falcom.co.jp', 443, :use_ssl=>true){|http| http.request_get('/'){|res| res.read_body{|c| p c.bytesize;  c.force_encoding 'UTF-8'}}}"

----------------------------------------
Bug #6436: Byte counting incorrect in BufferedIO (net/protocol.rb)
https://bugs.ruby-lang.org/issues/6436#change-80771

* Author: jcast (Jeremie Castagna)
* Status: Closed
* Priority: Normal
* Assignee: nobu (Nobuyoshi Nakada)
* Target version: 
* ruby -v: 1.9
* Backport: 
----------------------------------------
BufferedIO's @rbuf counts bytes with String#size, but should use String#bytesize. This creates potential incorrect reading of a HTTP body when changing the encoding of each chuck passed by HTTP#read_body:

http.read_body do |chunk|
  chunk.force_encoding "UTF-8"
end
