How Does ASP Encode UTF-8 Data ?

[Arnold Shore]

Can anyone explain how ASP encodes UTF8 data? I'm posting single-character
Cyrillic from an HTML page to an ASP, and the 2-byte test characters come up
as 4-bytes each. As follows:

&H04 4D comes up &HD1 00 8D 00
&H04 4E comes up &HD1 00 7D 01
&H04 4F comes up &HD1 00 8F 00

The algorithm I'd tried worked OK for the first and third example above, but
it fails for the second. (No, two out of three IS bad.)

Thanks, all.
