Unicode problems with saved file and Google cached version

Archived from groups: microsoft.public.win2000.file_system (More info?)

No problem with this file until I added some foreign script
and saving to unicode.

Google Cached is mangling the cached version of my site
http://www.divdev.fsnet.co.uk/dysch.htm
(medical self-help group)
but only since adding some foreign text
but I cannot find what the problem is.
I've tried queries to alt.html and
http://groups.google.co.uk/group/g [...] rt.general
and searching general internet but no solution found.

I doubt it is a problem with freeserve (fsnet ) site as
someone else's site
http://www.purplepalace.fsnet.co.uk/nicklivedates.htm
These symbols also appear at the top
ÿþ
and looking in the Google cached source code of its header has interpreted
as usingcharset=ISO-8859-1
although that file contains no foreign script at all as far as I can see.
(I've tried emailing that person but no reply )

This is someone else's fsnet file that contains a lot of foreign script
but is not mangled on Google cached
http://www.hinduism.fsnet.co.uk/na [...] shna_lokan
atha_stotram.htm

Whether I save as Unicode in Notepad or Word I see no spurious characters
added to the file when viewed in Word or Command Prompt / Dos / Type
command.
But Google seems to see these ÿþ characters. Is the problem
with Windows 2000 and Word/Notepad or a problem with ftp ?
