Expected Behavior
I would expect Time to return as UTF-8 or US-ASCII like how JRuby 9 and MRI Ruby 3.4 do.
JRuby 9.4

US-ASCII
Actual Behavior
JRuby 10 returns Time as ASCII-8BIT

$ ruby -e 'puts Time.now.iso8601.encoding'
ASCII-8BIT
I believe this behavior may be an unintended side effect of the native Time#xmlschema (iso8601) added in JRuby 10.0.1.0 (see PR here).
Thanks!
