There appears to be a bug with the encoding of interpolated strings on 1.9.3.

Here is a comparison of versions:

1.9.2
-----

ruby-1.9.2-p290 :001 > a = ""
 => "" 
ruby-1.9.2-p290 :002 > a.encoding
 => #<Encoding:UTF-8> 
ruby-1.9.2-p290 :003 > "#{a}".encoding
 => #<Encoding:UTF-8> 

1.9.3-head
----------

ruby-1.9.3-head :004 > a = ""
 => "" 
ruby-1.9.3-head :005 > a.encoding
 => #<Encoding:UTF-8> 
ruby-1.9.3-head :006 > "#{a}".encoding
 => #<Encoding:ASCII-8BIT> 

ruby-head
---------

ruby-head :003 > a = ""
 => "" 
ruby-head :004 > a.encoding
 => #<Encoding:UTF-8> 
ruby-head :005 > "#{a}".encoding
 => #<Encoding:UTF-8>
