that which the operating system is using, which is available
on theFile class asFile.systemCharset:
stream.writeMultiByte( document.getElementById
( "txtNote" ).value, air.File.systemCharset );Once the text has been written to the file, it is important to
close the file to avoid any corruption or blocking of access
from other applications. Closing a file is accomplished using
theFileStream.close( ) method.
TIP
XML data is already in textual format and, as such, can
be written to disk using these same series of steps. If the
application uses theXMLHttpRequestobject, then a using
themyXml.responseTextproperty alone may be adequate
for most situations.<html>
