When I develope a flex application, I can type Thai characters in windows in TextBox without any problem. Windows shows thai characters properly. However, after I deploy my application on the webserver and access the application via Mac or Linux. Flex seems not to show thai character properly. I am sure that the other foreign languages have this problem as well.
Somebody please help.
It may depend on which font you are using and how those fonts are supported on other platforms. Try different fontFamily names.
