I tested with the Microsoft 'Verdana' font, which I know to work very reliably
in any other case. If the TTF handling is OS-specific, shoulden't it be handled
in this way, then?

How could the OS ray-trace a TrueType font character? If it could, POV-Ray
would not be needed. The OS can draw the text on screen for itself and
other application correctly because it knows all the users settings, but
POV-Ray has to take the raw TrueType font file, read it, analyze it and make
a 3D object out of it.
In any case, did you try my suggestion? Did you check Jon's suggestion if
"notepad" really write a UTF-8 text file?

Notepad supports UTF-8 in the Windows NT series only. (There's an extra
"Encoding" drop-down box under the "Save as file type" one.)

Which NT?
When I was using NT4 at work a while back, it only did 16-bit, not UTF-8.
Could have been a SP thing.

UTF-8 editor
------------
The POV-Team seems to say you need to be sure to write UTF-8
files, because POV cannot read UTF-16 files.
I know of one such program: Vim. Yes, it's a Vi clone, so you
might not like the way it works. But you don't need to do much
work there, and gvim has a graphical interface. Open the file
with it, type
:set fileencoding=utf-8
and then
:wq
to write it and quit the editor.
Vim 6.0 is still in beta (for only a few more days) and is
available from Vim FTP mirrors in the unreleased/pc directory.
Take the gvim60ax.exe file.

At last - a useable hint! I tried the raw character code with "\uXXXX" and a
little help from Character Map, and it worked! I must admit that I still have
very limited knowledge of UTF8 coding, but I have noticed the 'unicode'
markings in Character Map. I could never have guessed the \u-part by myself.
Thank you very much for this information. You have been very helpful.

Hmm, while it is good that this works (so at least the TrueType rendering
works), I am still worried because of the UTF-8 problem. If notepad indeed
claims it writes UTF-8, could you ZIP a (small) sample file with lots of
non-ASCII characters and post it in beta-test.binaries, please? It would
help to find out what is wrong if the file is UTF-8.

It is UTF-8, but it starts with EF BB BF, the UTF-8 encoding of the FFFE
endianness indicator (as written on an Intel machine, obviously. A Motorola
machine would use EF BF BE) We could easily interpret the presence of those
three bytes as an implicit UTF-8 charmap, and infer the endianness of the
other UTF-8 characters in the file at the same time.

Ah, of course, if it is a whole UTF-8 file. I will fix it in the next few
weeks.

Actually, UTF-8 is byte-order independent. So the UTF-8 BOM will always be EF BB
BF.

http://www.unicode.org/unicode/faq/utf_bom.html
I had just run into this on some Java related issues.
Basically, the BOM is a special use of a standard "ZERO WIDTH NON-BREAKING SPACE"
character. Sometimes it might be treated as a BOM (or UTF-8 flag) and stripped out,
but it doesn't have to be. At the begining of a file it's probably a good idea,
though.
