Well i have tried to find the answer by myself and i had no luck at all, so here it is:
i have followed all the tips i have found here and there, putting <% # coding: UTF-8 %> using encode and force_encoding even trying some wacky regex i came up with (which of course was a dumb idea)
i am using ruby 1.9.2p290 and Rails 3.0.3
i have no clue at all what is wrong
the crazy part of this is that the line where the error happens is an URL...
ActionView::Template::Error (invalid byte sequence in UTF-8): 52: <tr class="<%= cycle("row-odd", "row-even") -%>" title="Direccion de la informacion."> 53: <td> URL </td> 54: <td> 55: <a href="<%= entry[:original_url] %>" target="_blank" title="<%= CGI.unescape( entry[:original_url] ) %>">Abrir en nuevo tab.</a> 56: </td> 57: </tr> 58: app/views/main/results.html.erb:55:in `block (2 levels) in _app_views_main_results_html_erb__4329752108549495342_44926400_4357034463775245520' app/views/main/results.html.erb:33:in `block in _app_views_main_results_html_erb__4329752108549495342_44926400_4357034463775245520' app/views/main/results.html.erb:23:in `each' app/views/main/results.html.erb:23:in `_app_views_main_results_html_erb__4329752108549495342_44926400_4357034463775245520'
