Hello, I'm a newbie.
I'm doing some tests to change the original font on my prs-650, with Calibre.
I'm converting some lrf files to epub, using the fontin font as indicated
here
It's working: the text is in fontin, but is also in bold letters (I suppose the original lrf files are in bold, so Calibre isn't changing that)
My question is: what's the code I have to give to Calibre to override the lrf bold and have regular fontin in the epub.
Thanks (I suppose the question has already been asked but I can't find the answer with the search engine

)
