Unicode chars in method names aren't accepted #3778
Description
Environment
JRuby version:
jruby 9.1.0.0-SNAPSHOT (2.3.0) 2016-04-01 30c1276 Java HotSpot(TM) 64-Bit Server VM 25.60-b23 on 1.8.0_60-b27 +jit [darwin-x86_64]
OS:
Darwin escher 15.3.0 Darwin Kernel Version 15.3.0: Thu Dec 10 18:40:58 PST 2015; root:xnu-3248.30.4~1/RELEASE_X86_64 x86_64
Expected Behavior
Unicode chars in method names should be accepted.
I discovered this issue with hanami-utils and patched it to make the build to pass with 9.0.0.0.
According to @enebo, this supposed to be fixed with nightly series, but it isn't the case.
MRI/expected behavior:
irb(main):001:0> RUBY_VERSION
=> "2.3.0"
irb(main):002:0> def тест
irb(main):003:1> puts "hi"
irb(main):004:1> end
=> :тест
irb(main):005:0> тест
hi
=> nilActual Behavior
irb(main):001:0> RUBY_VERSION
