wow! it's very interesting.

Certainly, the latest mri tests(https://github.com/jruby/jruby/actions/runs/3113604144) finished in 20-30 min.

@headius please review PR(https://github.com/jruby/jcodings/pull/31) This PR fixes caseMap for Georgian. I think you can remove the following exlclude tag. ``` test/mri/excludes/TestCaseMappingPreliminary.rb exclude :test_georgian_capitalize, "unfinished in initial 2.6 work, #6161" ```...

@headius @lopex please review PR(jruby/jcodings#32) This PR fixes treeStart for From_UTF8_MAC_Transcoder I think you can remove the following exlclude tag. ``` TestTranscode.rb exclude :test_utf8_mac, "needs investigation" & TestCSVEncodings.rb exclude :test_reading_with_most_encodings,...

@headius @lopex please review PR(jruby/jcodings#33) This updates UTF32Encoding. I think you can remove the following exlclude tag. ``` TestUTF32.rb exclude :test_mbc_newline, "Java ArrayIndex error" ```

@headius Thank you.

I create 2 PR(jruby/jcodings#34 and jruby/jcodings#35) to reduce TestTranscode failures.

@headius No, I don't have any patches now. But I'm investigating other encoding test cases.

@headius I create #6211 and jruby/jcodings#36 . I believe these will fix `test/mri/ruby/test_transcode.rb` failures.

@headius I create jruby/jcodings#37 to reduce EncodingTest failures again.
