This is a question about Calibre E-book Viewer, not the Editor. I found no sub-forum specifically on the Viewer, so I am posting here because it's about a problem rendering text and may exist in the Editor as well.
Specifically, if I open some e-books in Calibre E-Book Viewer, some characters in the text do not render properly. This often happens with characters that are Spanish or German, and have umlauts or tildes over them.
For example, here is a screen grab of a page from an e-Book viewed in Calibre E-Book Viewer:

Note that names with non-English characters are mangled. In this example, the letter ñ (n with a tilde over it, like in the Spanish word niño or señorita) is mangled.
This does not happen in other E-Book Viewers. Here is the same page from the same E-Book in the Adobe Digital Editions Viewer:

Adobe Digital Editions Viewer renders the characters correctly while Calibre E-Book Viewer does not.
I thought it might be a problem with the font, that perhaps the font used doesn't have the glyphs for these Spanish or German characters. But I tried changing the font to Times New Roman, which I know contains these glyphs. The problem still remains.
Does anyone know why this is happening? How do I correct this issue?
Thanks.
