What encodings does Saxon support with unparsed-text()?

Hi Folks,

The Saxon documentation says this about the unparsed-text() function:

unparsed-text($href as xs:string?, $encoding as xs:string) --> xs:string?

Arguments

$href		xs:string?	The URI of the text file to be read

$encoding 	xs:string 	The encoding to be assumed for the text file

As I understand it, if the file pointed to by $href is encoded as Windows 1252 and $encoding has the value "Windows-1252", then Saxon will input the Windows-1252-encoded text and convert it to Unicode, right?

In other words, Saxon takes the input text and uses $encoding to inform Saxon of the text's encoding, and then converts the text to equivalent text that is in a Unicode encoding scheme, right?

What character encoding schemes does Saxon support? Can Saxon convert Windows 1252 text to Unicode? What else?
