System.useCodepage that bad?

I was having troubles loading some ASP variables into flash because they contained international characters (á, ã, ó). I tried using the server.URLencode(variable) asp function and saving as UTF-8 but none of this seemed to help me out.

I have read in many different places (moock.org for example) that System.useCodepage=true; should be avoided whenever possible, but in this case it fixed my problem. So I am wondering, is there a way around this(changing the code page) or should I leave it as it is? How bad is this?

Thanks,
