I have a book in ePub format. It is an English book, but with several words with non-English characters. They are correctly rendered in Calibres's reader, but not in my PRS-650.
For instance, this sentence
"The Anthrōpos in Heaven..."
is rendered OK in Calibre, but appears as
"The Anthr?pos in Heaven..."
in my PRS-650.
The corresponding HTML section looks like this:
<span class="italic"> Anthrōpos </span>
The character ō is coded in UTF-8.
I suppose I could fix it using some kind of <span lang="EN-US"> around "Anthrōpos", but which language code should I try? Anthrōpos is not English, but it is not Greek either, it's Greek transliterated to "almost" ASCII characters.
