Issue #20929 has been updated by YO4 (Yoshinao Muramatsu). Thank you for your response. Regarding Time#zone encoding, I am experimenting with it in my branch https://github.com/YO4/ruby/tree/tzname_utf8. I found this issue in my research for that. At present, the change to utf-8 causes the following error. ```
ruby -e 'puts "タイムゾーン:#{Time.now.zone}"' -e:1:in '<main>': incompatible character encodings: Windows-31J and UTF-8 (Encoding::CompatibilityError)
To resolve this, other strings must also be in UTF-8 encoding.
I think it would be preferred that strings with Unicode code ranges also have UTF-8 encoding. OS-derived strings, excluding I/O content, seem to meet that requirement.
Of course, this matter should be discussed in another issue.
Thanks.

Bug #20929: TestTime have an assertion different from current implementation.
https://bugs.ruby-lang.org/issues/20929#change-110869
* Author: YO4 (Yoshinao Muramatsu)
* Status: Closed
* Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
test/ruby/test_time.rb have following assersion function.
```ruby
def assert_zone_encoding(time)
zone = time.zone
assert_predicate(zone, :valid_encoding?)
if zone.ascii_only?
assert_equal(Encoding::US_ASCII, zone.encoding)
else
enc = Encoding.default_internal || Encoding.find('locale')
assert_equal(enc, zone.encoding)
end
end
In current implementation, Time#zone are returned in US_ASCII or locale encoding, which does not seem to take into account the default_internal. ``` C:\>ruby -e "puts Time.now.zone" 東京 (標準時) C:\>ruby -e "puts Time.now.zone.encoding" Windows-31J C:\>ruby -EWindows-31J:UTF-8 -e "puts Time.now.zone" 東京 (標準時) C:\>ruby -EWindows-31J:UTF-8 -e "puts Time.now.zone.encoding" Windows-31J ``` -- https://bugs.ruby-lang.org/
