Its not so much whether or not the xhtml files support the Greek entities (BTW, they do) but rather whether the particular reader's (device or app) fonts support the characters.
I did a quick test using your post (saved "source" from my browser and trimmed it to just the post's text along with a minimal HTML document structure), converting it to both ePub and MOBI using calibre v0.8.39 on WinNT. The resulting ePub displayed the Greek characters correctly in both Sigil and ADE (I don't have an ePub device to test with). The MOBI displayed properly in both Kindle Previewer v2 and on my Kindle3. In all cases, there were no special fonts added or specified. The files are attached (the ZIP file is my HTML edited version of the post's "source").
You should be able to edit your ePub using Sigil to replace the incorrect characters with the proper Greek characters, copying them from my ePub if need be.
