Marshal.load returns escaped non-ascii characters in symbols

[deepj]

I know, a bit weird to use non-ascii characters in symbols but MRI returns an expected result.

MRI (2.5.3):

irb(main):001:0> a = [:â]
=> [:â]
irb(main):002:0> Marshal.load(Marshal.dump(a))
=> [:â]

TruffleRuby (1.0.0-rc10):

irb(main):001:0> a = [:â]
=> [:"â"]
irb(main):002:0> Marshal.load(Marshal.dump(a))
=> [:"\xC3\xA2"]

This bug is inherited from Rubinius's marshal.rb. Should be relatively easy to fix.

Fixed in 2f4ba36 and added specs for it as well as for serializing objects with multibyte instance variable names. It will be in the next release.

@deepj This is fixed in the new 1.0.0 RC 11 release, and verifying from IRB looks good. Please comment here if you're still seeing a problem.
