How to recreate the issue:
In order to recreate the problem simply put an HTML input text box into a form.
When filling out the data in the browser on a windows box type ALT-0225 .
Then submit the form. The value will not be retrieved correctly. The only
work around I could come up with was to do this:
if (fileItem.isFormField())
{
String value = fileItem.getString("UTF-8");
}
But unfortunately this implies that you always have UTF-8. It seems to me that
the file upload library should account for the encoding in the method
".getString()" for FileItem. But since the encoding is always "ISO-8859-1"
there is no way to work around this issue. There are many questions on Stack
Overflow talking about this issue. It seems to be a common problem for people.
It is very common to have UTF-8 encoding these days especially at Universities.
Thanks,
Lance

Hello,
http headers are essentially ASCII. Especially for things like the boundary.
The arguments (filename) might be QP, but not all browsers like that.
