example:

without the utf8 option i've the following errors:

Possible Parse Error: Non-ASCII character has been replaced by space
character.
File: etat.txt  Line: 4
Possible Parse Error: Non-ASCII character has been replaced by space

with the option, the precedent errors disappear, but i've got new ones:

It seems that the font you are using does not include this letter. Each 
font does only provide graphics (they're called glyphs IIRC) for a 
limited subset of all letters. You'll have to choose a different font or 
letter to solve the problem...

To see which glyphs your font provides, use the font-viewer of your 
operating system.


HTH,
Florian

Was going to suggest checking with UnicodeView http://www.lischke-
online.de/FontViewer.php then realized that since UTF8 is supported, but 
Unicode isn't (I think), it probably doesn't do any good at all. :( 
Still, useful gadget to have around.

That's odd. I vaguely remember using non-standard characters before using
[alt + ####]. Alt-130 shows the character in the text editor, but it
doesn't render. Try just putting a ' over an e.

global_settings{

}

#declare title = "Su00e9rie";


And as suggested by Florian, i've changed my font to Arial.ttf then it
works...

Thanks for your help

I've always been able to create text objects including letters with marks
like accents, tildes, diaeresis, etc., just denoting them with their

"charset" sentence in "global_settings"...
Moreover, I've written an include file declaring string variables, each one
containing a single Unicode character.

FYI, UFT8 *is* an Unicode encoding.

How can it be, given that it doesn't allow access to all unicode 
characters? It by definition can't, since true unicode requires a 
'section' code, followed by a 'character' code, of *always* two bytes. 
UTF8 treats only specific characters as a 'section' code, so part of the 
unicode set if unavailable. Unless I am completely missing something... 
But I have seen people complain before about how they can't use some 
character with POV-Ray and the reason always given is that UTF8 doesn't 
support them. If I am wrong, then why does this problem crop up all the 
time?

There is no such thing as a "section code" in Unicode. Unicode defines one 
continuous set of character codes. UTF8 is an encoding of Unicode, providing 
access to all Unicode character codes. You definition is clearly wrong; I 
suspect you are confusing Unicode with "code pages" from long forgotten DOS 
and early Windos times.

Because* people do not realise that most editors, including those included 
with POV-Ray for Windows and POV-Ray for Macintosh do *not* save text files 
in UTF8 but ISO-8859-1 and MacRoman respectively.  As such, entering any 
character outside the ASCII range and setting "charset" to "utf8" causes 
POV-Ray to try to interpret those an UTF8 sequences, which they are not. 
This of course yields all kinds of strange errors, with POV-Ray rejecting 
characters many times, or replacing them with blanks after issuing a warning 
(it depends).

* This applies to POV-Ray 3.5 and later only.

No, I am not confusing them, I just don't know the right term, so guessed 
at one. But to be clear, what would this $2039 be in UTF8? Would it be a 
space and a 0, or the 0/00 symbol? If the later, then Ok, sorry for the 
confusion. If that is the case, then we need to fix the editor so it 
correctly supports the characters.

Sounds like there are serious bugs in the support.. Maybe a binary field 
type would be useful, like the html # numbers? It seems quite ridiculous 
to support it, but have that support be effectively broken.
