Hello, I have problem with charset in TabPanel. I dynamically load url with charset=windows-1250. I can't change this encoding and national characters are deformed in TabPanel. Is any way what to do on client side? For example converting encoding? I checked Ext.Ajax.on('requestcomplete', function(conn, response, options){ alert(response.responseText); }); but charactes are defordem here too. Thank you for help.
