[XeTeX] XeTeX and code page 65001

[Philip TAYLOR]

Trying to help Natércia Fernandes with her query regarding
Portuguese hyphenation on TeXhax today, I had occasion
to try the following :


	C:\>xetex
	This is XeTeX, Version 3.1415926-2.2-0.9997.4 (Web2C 2010)
	 restricted \write18 enabled.
	**\showhyphens {natércia}
	
	! End of file on the terminal... why?


If I carry this out in Win/XP's normal catcode régime, all proceeds
normally but the output is corrupt at the point of the accented
character; if I try the same thing with Lucida Console selected
as my CMD font and the code page changed to 65001 (Win/XP's number
for UTF-8) so that I can see the accented "e" in Natércia's name
correctly, I get instead the above "end of file" message.

Can anyone hazard a guess as to why ?
