Bug #5379: the join method of array return different encoding result
http://redmine.ruby-lang.org/issues/5379

Author: saber ma
Status: Open

Target version: 1.9.3
ruby -v: ruby 1.9.3dev (2011-09-23 revision 33323) [i686-linux]


ruby-1.9.3-rc1 :001 > [[], "������"].join
 => "������" 

This is fine. But is the last element is nil, the result is different.

ruby-1.9.3-rc1 :002 > [[], "������", nil].join
 => "\xE4\xB8\xAD\xE6\x96\x87" 

It will cause some gems to raise error: incompatible character encodings: UTF-8 and US-ASCII

This bug can be reproduct in ruby1.9.3 preview1 and rc1, but ruby1.9.2 p180 and p290 is ok.


ruby-1.9.2-p180 :001 > [[], "������",nil].join
 => "������" 
ruby-1.9.2-p180 :002 > [[], "������"].join
 => "������"
