Subject: [ruby-core:93833] [Ruby master Bug#8611] Minitest encoding problems.

Issue #8611 has been updated by jeremyevans0 (Jeremy Evans).

Backport deleted (1.9.3: UNKNOWN, 2.0.0: UNKNOWN)
Status changed from Feedback to Closed

The issue you described with irb crashing was fixed between 2.0 and 2.1:

```

Bug #8611: Minitest encoding problems.
https://bugs.ruby-lang.org/issues/8611#change-79705

* Backport: 
----------------------------------------
A long standing annoying misfeature of minitest is the problem with encoding, which I have solved by patching the backtrace.join line in units.rb, #puke method with map{ |str| str.force_encoding( "UTF-8 ) }. If I don't do this, the tests in irb won't run, instead I get a complaint about "ASCII 8" versus "UTF-8" incompatibility. Only happens when one extensively uses UTF characters when coding, an annoying intermittent error.
