I just found out how to setup epub file to use standard LRF fonts.
This is the line you need to add to your recipe:
Code:
extra_css = '@font-face {font-family: "serif1";src:url(res:///opt/sony/ebook/FONT/tt0011m_.ttf)} @font-face {font-family: "monospace1";src:url(res:///opt/sony/ebook/FONT/tt0419m_.ttf)} @font-face {font-family: "sans1";src:url(res:///opt/sony/ebook/FONT/tt0003m_.ttf)} body{text-align: left; font-family: "serif1"} .article_date{font-family: "monospace1"} .article_description{font-family: "sans1"} .navbar{font-family: "monospace1"}'
