I know this is my 2nd post regarding EPUB converting Chinese, I think posting another is easier to understand...

These 2 days I tried using Calibre 5.0 to convert Chinese books into EPUB format. It actually works well, but only on PDFs so far...
I did not do anything to my PRS505, just use the universal flasher flashed into Chinese fonts which work perfectly with Chinese LRF I made witt Calibre.

The steps I made the EPUB are all the same with making LRF, except a little extra:
1. Set output format to EPUB - of course.
2. After click“Convert Ebooks", In "Look&Feel" option, paste code below into“Override CSS”

@font-face { font-family:"Swis721 BT"; src:url(res:///Data/fonts/tt0003m_.ttf), url(res:///tt0003m_.ttf); }

body {
font-family: "Swis721 BT", serif;
}

The Chinese PDF(not fonts embeded) books are very nicely been converted to EPUB, but TXT and HTML were convert to EPUB with all "????". Any idea?

Use the encoding setting when converting txt and html to specify the character encoding the original files are in

Use the encoding setting when converting txt and html to specify the character encoding the original files are in

Thanks! I will try it..
Question: What should I put in "Source Encoding"? "Unicode" or "ANIS"?

Another question: Why it's missing a few letter at the right edge?

OK, thanks for kovidgoyal's answer, I managed to convert a TXT file successfully. I don't know what's the code name of UNICODE and ANSI, as I saved the TXT in these 2 code and put the name in the command line, it does not work.
So I tried UTF-8 txt, it's working!

But HTML, I use IE to open the TXT file, and save as UTF-8 HTML, no luck in Calbire
