[Discuss] EPUB Ubuntu Calibre Android Issues

[pw]

Hello,

I have an odd problem that I am not sure how to fix.

I am converting some e-books to EPUB format so they
can be read on a small Android tablet.

When the books are converted, using Calibre, from my local Ubuntu
library they look just fine using the e-book reader in Calibre
and also using lrf-viewer alone.

The problem appears when the books are opened in Android using
'ereader' or 'coolreader'.  Anything with underlining or containing
mark-up characters  comes up with blobs of gobbeldy-gook characters
mixed into the text.

The books are being converted using UTF-8 as the output
and all underlining looks just fine in Ubuntu.

I am not fully acquainted with Android in all it's forms
so I  am unsure if there is an OS mod or something that should fix
the issue. I looked to see what settings Android is running under
and they also appear to be UTF-8.

Does anyone have any experience mitigating e-book junk characters
on Android?

Thanks

Peter
