Thai Language incorrect present when load from CSV file to data-grid

I have a language-problem in Loading CSV file to grid-data by following detail :

1. I used file basic.htm in folder examples/grid data csv - text file for testing.
2. I edited csv-file,named "companies1.csv" by changing "Oracle Corporation" to "Oracle Corperation ÀÒÉÒä·Â", Adding Thai-Language 3. When I cheecked a result in my browser,IE7,then found a grid-data presented rectangle character insteaded Thai-Language 4. No-problem for javascript-array in Thai-Language.

Additional :
I bought Standard Edition License, Order No. = 23763686

Regards,

The CSV file must be in UTF-8 encoding for any non-Latin text. Open the file in Notepad and use File-> Save As... menu with UTF-8 encoding in the bottom select box instead of ANSI. It seems that Excel always saves CSV files in ANSI encoding and Thai characters are lost.

Dear Support,
Problem solved. Thanks.
