I have run accross an odd situation. I was trying to do some greek 3d
lettering with pov-ray but when I tried to use the font (a greek font dl'd
from a Christian site) I didn't get greek characters. Instead I got what
looked like a 1 and then some digital looking 0's (it may have been boxes
I'm not sure). Trying the standard windows symbol.ttf I got the proper
results. My question is, does povray require the font's to be 32-bit win95
fonts? I think the first font I tried was a win3.x 16bit font.

Before you go blaming POV :) try looking at each glyph with either a font
editing
program (check the links) or any font renderer.
ie the font viewing prog that comes with windows or the freetype renderer
plugin that comes with The Gimp.
Note that some normal win32 fonts won't work with freetype.

You may be able to fix the font by mucking around with the font's table
type(unicode/windoze/macsomething) using a font editor.

BTW AFAIK those boxes are usually the glyph for characters that the font does
not define.

other than that I dunno

Only characters in ASCII range (character code 0 to 127) are supported
in POV-Ray 3.1.  The boxes you see are default characters that will be
displayed when the corresponding character could not be found in the
font by the search method that POV-Ray uses to find a character inside
the font file.

My machine came with three greek TTF fonts. Two of them (greekc__.ttf
and greeks__.ttf) work correctly in POV, and one (versafontgk.ttf)
produces the effect you mention but also produces warning messages like 
"Character 67 (Ox43) not found in c:\windows\fonts\\versafontgk.ttf"
for each character in the text string.

POV uses the freetype libs? Where could I get the freetype renderer plugin
for the gimp?

Right, except that the characters I am trying to use are defined for that
font.

The characters I was using were "b" "s" and "u" I tried both upper and lower
case.

Well I didn't get the results I'd hoped for out of symbol.ttf so I chucked
that idea for the time being. I will however go back and check the messages
for those renders and see what I got.

Yes, but as you said you are using a Greek font.  The ASCII table just
defines Roman characters.  While Greek may occupy the same "namespace"
(or call it character code), they are still stored in a different table
inside the font, and POV-Ray simply does not search this table.

In POV-Ray 3.5 you will have access to all 16 bit Unicode characters,
however, even then just entering Greek characters in a text editor and
using a Greek font won't work.  There is no way for POV-Ray to know the
intended font table you want to use, and adding every possible one (lets
just say there are more than) is not possible.   What you will have to
do is use a Unicode export capable text editor (maybe CodeMax on Windows
supports Unicode, but I don't know that) and save your scene files in a
format called "UTF 8".  Alternatively, and if you need only very few or
very special characters, it is feasible to use one of the Unicode font
mapping tables available at <http://www.unicode.org/charts/> and
manually insert the hex codes, for example \u0394 for the Greek capital
letter delta.  But, as said, you will have to wait a few weeks (or more)
for POV-Ray 3.5 ...

I see. So that's how it works. I just assumed that the ascii values were the
same.

I'm definitely breathlessly awaiting 3.5 now. Now will 3.5 have isosurfaces,
or will I still have to get an unofficial patch to do that?

There will be isosurfaces in 3.5.

I had already, and since I couldn't remember if isosurfaces was on the list
off the top of my head I asked ^_^.

I've rendered plenty of wing dings and such.

The boxes are glyphs for non-defined fonts.  This can occur with a font set
that only has upper case defined and you try to use a lower case character,
for instance.

I think that's the version I have, I'll check into it.

a)there is a character for every letter I used when I vew the font in the
windows font viewer b)I've used at least one of the fonts in a couple of
word processing programs c)I've used one of the fonts with out trouble in
breeze designer d)I've used on of the fonts to do stuff in ms-paint, psp3,
and I think possibly the win32 gimp. d)one of them I got off of an online
bible site, so I'm pretty sure that they would define all the letters for
the font (or at the very least the ones they use, and this being a greek
font...........)

Pretty convincing.
I do think you should make a backup of the font & muck around with the tables
in a font editor though or you could wait for 3.5 :).
Or you could render an anti-aliased image in psp/gimp & use it for a height
field.

All this is irelevant to determine if the font is usable in POV-Ray 3.1.

a) POV-Ray does not use any Windows code to get the font data.
b) These programs use Windows to draw the font, so see a).
c) Breeze Designer is platform specific, so it knows that it is dealing
with Windows fonts.
d) All three use Windows to draw the font, see c) and a).
e) As said in a previous post, that the font contains certain characters
in a certain mapping does not say POV-Ray can or will use this mapping
when searching for a character.

Right, I figured that, I was just stating evidince that the character was
defined at said point.
