Hello gentlemen,

I’ve forced to such unicode problem:  
I have:  
\<%= text\_field\_tag ‘search’, nil, :id =\> ‘search’, :size =\> 10 %\>  
\<%= observe\_field ‘search’,  
:url =\> {:controller =\> ‘article’, :action =\> ‘search’},  
:with =\> “‘terms=’ + escape(value)”,  
:update =\> ‘search\_results’,  
:loading =\> “Element.show(‘search\_spinner’)”,  
:loaded =\> “Element.hide(‘search\_spinner’)”  
%\>  
in my article view, after sumbitting I get sequence like  
u0444u0438u043bu043eu0441u043eu0444u0438u044f in controller  
(params[:terms]).  
How can I convert it into normal unicode? I am using UTF-8 as encoding.

Thanks,  
Mikhail

instead of escape()

> :with =\> “‘terms=’ + escape(value)”,

use encodeURIComponent(), which should work fine with UTF8:

encodeURIComponent(‘Ñ?илосоÑ?ия’) =\>  
%D1%84%D0%B8%D0%BB%D0%BE%D1%81%D0%BE%D1%84%D0%B8%D1%8F
