Subject: [ruby-core:56105] [ruby-trunk - Bug #8611] Minitest encoding problems.


Issue #8611 has been updated by boris_stitnicky (Boris Stitnicky).


All right, I am no longer getting the same error since I patched it for myself, but to illustrate what I am talking about, here is another way to crash irb in basically the same way, pointing to a wider problem. It can be illustrated with Pyper gem that I wrote as follows:

gem install 'pyper'
a = [1, 3, 4, 3, 0, 3, 1]
a.��s��( :uniq ).��Oix��.��riXg��mE��

NoMethodError ensues, that crashes the irb:

NoMethodError: undefined method `map' for 0:Fixnum
/usr/local/lib/ruby/2.0.0/irb.rb:526:in `join': incompatible character encodings: ASCII-8BIT and UTF-8 (Encoding::CompatibilityError)

Bug #8611: Minitest encoding problems.

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.
