[FIXED] ruby encodings... can we word this error differently?

error.sh

$ irb
ruby-1.9.2-p180 :001 > "“"
 => "“" 
ruby-1.9.2-p180 :002 > "“".encoding
 => #<Encoding:UTF-8> 
ruby-1.9.2-p180 :003 > "\“"

Hi,

This issue is not yet fixed ! I am getting the same error message in 1.9.3p0.

[akshatha@localhost chiliproject]$ ruby -v

Just checked it in irb... it's fixed in Ruby at least:

ruby-1.9.3-p0 :001 > "“"
 => "“" 
ruby-1.9.3-p0 :002 > "“".encoding
 => #<Encoding:UTF-8> 
ruby-1.9.3-p0 :003 > "\“"
 => "“" 

What do you get if you use irb as above?

Hi, Thanks for reply. I got out put as below.

Hi Nagaraj, your irb session shows that the underlying problem with escaped UTF-8 has been fixed as I originally reported it. The higher level error you are seeing "Error during failsafe" is a rack or Rails error in your application and likely has a different root cause.

Good one..Clear explanation..Thanks to the author..
