Charset "iso-10646-1"

Greetings,
In attempting to build Spanish web pages I encountered a problem 
during printing from (Netscape 4.x on Macintosh OS).  I found that 
Netscape (Mac) would render the characters on screen, though would 
not print correctly when using charset=iso-8859-1.
I searched the web for other Spanish sites specifying a meta 
http-equiv character set, unsuccessfully.

I found charset=iso-10646-1  on W3C website 
(http://www.w3.org/TR/html4/intro/intro.html#h-2.3.1).
This seemed to fix the previous printing problem that correctly 
displays and prints, however when validating at W3C I get the 
following error:
----
Server: Apache/1.3.6 (Unix) (HURLinux) mod_perl/1.21
        Character encoding: iso-10646-1

A fatal error occurred when attempting to transliterate the document 
charset. Either we do not support this character encoding yet, or you 
have specified a non-existent
character encoding (typically a misspelling such as "iso8859-1" for 
"iso-8859-1").

The detected charset was "iso-10646-1".

The error was "".

QUESTION 1:
I am writing asking those with more experienced if this character set 
declaration is correct?
I am wanting the Spanish language allowing the display of special 
characters (eg. í and ñ ) during printing.
IE doesn't seem to have this problem.

Also

QUESTION 2:
I assume I can validate such pages with "charset=iso-8859-1" then 
change it to "charset=iso-8859-1" to assure conformance to W3C HTML.

Your time is respected and appreciated, thanks in advance.
