Trying to get UTF-8 to work

Warning: Missing charsets in String to FontSet conversion

Copy a text known to contains Greek characters (as rendered correctly in
my Opera Browser) nu tor phi (I think - anyway it was the nearest you can
get to 'utf' in Greek).

The actual bytes, filtered through 'od -xc',with escaped octal, are:
0000000 6c6f 6361 6c2e 7465 7374 2ecf 85cf 84cf
l o c a l . t e s t . \317 205 \317 204 \317
0000020 8638 0a00
206 8 \n
0000023

But if I view that in a supposedly en_US.UTF-8 window, it fails to display
those Greek characters (they are rendered as spaces), and yet if I attempt
to display characters such as the Danish ��� (shown in iso-8859-1 for this
message)
chl% echo ��� | od -xc
0000000 c3a6 c3b8 c3a2 0a00
� ** � ** � ** \n
0000007
they appear just fine. Moreover, I can type those Danish characters into
that window, but if I set the window to inout in Greek, nothing apart from
digits and punctuation appears at all (though the cursor moves as
expected).

So evidently, I am missing some font or font-conversion somewhere, but
where? Is there some package I have failed to load into my OS?

Apparently, Greek characters are missing in the font you are using.
For my xterms, I use some of the iso10646 character sets under Solaris,
e.g.

-misc-fixed-medium-r-normal--20-200-75-75-c-100-iso10646-1

which can be passed to the "-fn" option of xterm. I have never used dtpad
nor do I know how its font can be specified but there exists surely
a similar command line argument for dtpad.
