I used YUI to be Ajax framework for my project. YUI is no.1 for me. Now, I face some problem about Thai Languase. Let's me explain. I have autocomplete technic on my webpage. One page to be the search page, input keyword to search. The other page is database action, query data from MS-SQL and write the result to be XML. Both files are written by Classic ASP. I have test run on the web server. It's very good when I search for English character. But there is no response when I try to search for Thai character. I checked XML result, It's OK. Please suggest me how to solve this problem.
