epub w/ Greek on Calibre

How do I properly set up Calibre to automatically display Polytonic Greek characters?
I got this epub from the internet archive,
and it doesn't display any Greek at all. The pdf version under Foxit Reader,
for example, shows everything properly, then again it's an image scan of
the book pages.

epub (p.10.9 in Calibre):
Quote:
I have given a complete analysis of the rhetorical treatise known under the
name of the 'PrjTopinrj ^09 'A\e%ai>$poi', a work long attributed to...
pdf (p.20 bottom page in Foxit):


Apparently, each epub has a CSS stylesheet which can be viewed when
browsing the content of the epub with an archiving soft like winrar.
Here it is:
Code:
body {
    font-family: "Palatino Linotype", "Book Antiqua", Palatino, Georgia, "Times New Roman", serif;
}
h1,h2,h3,h4 {
    font-family: "Palatino Linotype", "Book Antiqua", Palatino, Georgia, "Times New Roman", serif;
}
p {
    font-family: Georgia,  "Palatino Linotype", "Book Antiqua", Palatino, "Times New Roman", serif;
}
img {
    display: block; text-align: center; margin: 1em auto;
}
The default settings in Calibre has Times New Roman for serif and Verdana for sans.
I tried changing the serif to Palatino Linotype and the sans to Arial Unicode MS, but that
didn't do anything.

A different epub, which I got from this site but can't find the link, has 38 pages of
unicode text examples (greek, hebrew w. vowelization, latin lorem ipsum) and it displays
everything without me fiddling with anything.
This particular file has different folder with the embedded fonts, and one with
the stylesheet, but the Internet Archive's epub did not have a folder with the fonts.

I uploaded it to megaupload (although it is from these forums; just can't
find the link):
http://www.megaupload.com/?d=ATAO469Z

One thing that was odd about this file is that Times New Roman,
as well as some other fonts, despite being completely Polytonic Greek-enabled,
did not display the accented letters.

I'm sorry if this has been asked before. I've searched and couldn't
find a solution I understood.

Any help would be appreciated.

You don't have to do anything to Calibre to get it to display characters, Greek or otherwise. If the EPUB is correct, and the font is available, Calibre will use it. It appears to me that the problem is in the EPUB, not Calibre. Does the EPUB you got from the Internet Archive display Greek characters when viewed with other EPUB viewing software?

I don't really know about any other reader. I only started using
Calibre because a friend recommended it and its support of epub format.

I've searched the internet and found Adobe Digital Editions.
It didn't show the Greek in the internet archive's book as well.
I've tried Sigil as well and it didn't show the Greek either.

So I guess the the problem is with this particular epub.
Fair enough. How do I modify the stylesheet so that it will display the
book exactly the way it was intended to be displayed?

Have you tried the file I uploaded to megaupload, unicode_font_display.epub?
On Adobe Digital Editions, just like in all of their products, Hebrew is either
not recognized or displayed backwards. The Greek characters in the font
examples were not viewed in most of them. How do I set the stylesheet to view at
least the Greek properly in the fonts which are capable of that?

Or better yet, if you or anyone else have a properly-set epub with Polytonic Greek
characters, It'd be of great help to me.

Thanks.

There isn't any way to get the greek from this document other than by viewing it as PDF or one of the other formats that is image-based.

The book was originally scanned to PDF as images, then processed by OCR. Each page in the PDF is an image, backed with hidden OCRed text. When you look at the PDF, you are seeing the image. Seeing the margin notes and annotations is further evidence that the image is being shown. When you select text, you are selecting the hidden text behind the image.

When Microsoft scanned it for the library, they made no attempt to switch fonts to greek, or even to recognize it. Instead, they let the OCR system find whatever characters it wanted to. This is a very reasonable approach, given that when looking at the PDF, one sees the image, not the scanned text, and given that attempting to render the greek would be extremely labor-intensive. However, it does mean that other formats that don't have the two-layer image/text structure will show near-match characters instead of Greek.
