Issue #2255 has been updated by Vit Ondruch.


For me, internal encoding doesn't matter, since the conversion is pretty easy. But important is that the following example will work properly:

C:\>echo puts ARGV[0] > uparam.rb

C:\>ruby\bin\ruby.exe uparam.rb ca_zufllige_luouk_ѧ٧ݧԧ
c?a_zufơllige_uuȹ̥ƥ_???????
