I use sumatrapdf as my daily viewer for ebooks especially with epub format
To shrink the file size, I usually remove all the font inside fonts folder in epub file. (for those interested, unlike european fonts, some asian fonts are large in size, including thousands of characters in multi writing systems)
but the viewer's default font is not easy on eyes and is ugly. I want to change it to something better, without embedding a font into epub file.
how do I achieve this? I am not about to move to another viewer when sumatrapdf is by far the fastest in loading the file and light in size on Windows machine.
any help is appreciated.
