Sorah Fukumori d2864ca330 [ruby/zlib] Zlib.gunzip should not fail with utf-8 strings ... (https://github.com/ruby/zlib/pull/55) zstream_discard_input was encoding and character-aware when given input is user-provided, so this discards `len` chars instead of `len` bytes. Also Zlib.gunzip explains in its rdoc that it is equivalent with the following code, but this doesn't fail for UTF-8 String. ```ruby string = %w[1f8b0800c28000000003cb48cdc9c9070086a6103605000000].pack("H*").force_encoding('UTF-8') sio = StringIO.new(string) p gz.read #=> "hello" gz&.close p Zlib.gunzip(string) #=> Zlib::DataError ``` Reported and discovered by eagletmt at https://twitter.com/eagletmt/status/1689692467929694209 https://github.com/ruby/zlib/commit/c5e58bc62a		2023-08-10 20:12:21 +00:00
