No.

Firstly, the character set in use here is Unicode. There is no need to
switch 8-bit code pages and so forth.

Secondly, that character set is being correctly labelled and correctly
recognised, so there is no worry about sniffing - the characters are being
correctly transmitted.

Thirdly, the default font may or may not have glyphs for Greek characters,
depending on the OS. For example, I am using Windows 2000 and the default
fonts do, indeed, have glyphs for Greek amongst others.

Fourthly, conformant behavious on encountering a character for which there
is no glyph is to display some symbol such as an empty box. However, if you
select that text, copy iit and paste it into an application that *can*
display it, the characters should all be preserved. It is an issue of
rendering glyphs, not of understanding characters.

Only if the browser misunderstands, or is not Unidode enabled, or the
content is incorrectly labelled, will one get "garbage characters".

Right, but you are free to purchase or download other ones. In general, the
language packs are providing additionaldisplay capability for the OS, as
well as just fonts.

Thats because they are providing a browser, not an operating system.

You could, but the exact same fonts used by any other application are also
available for use in Netscape.

Adapt in what way?

Right ;-)

This is completely unnecessary. And inded, for the sample page given as an
example, doing so would actually prevent the webfonts referenced in the CSS
being actually applied.
