Monospace Fonts on Kobo Forma

[danabrams]

Hi all, I know this is a common problem, but I've spent a week and a half trying to follow the instructions on other posts to get monospaced fonts working on my Kobo Forma and it's just not working.

I've successfully installed patched firmware, I see the various Courier fonts I've installed as options in the fonts menu, and I've tried modifying the CSS via Calibre, but no matter what I do, I can't get monospaced fonts to work.

Since the primary use is to read programming books for work, this is frustrating to say the least. It works in plato, but not in the main reader.

Any help?

Is your book kepub or standard epub by the time it arrives on the Forma?

Which patch(es) have you enabled? Post the patch code you used.

What does the book's HTML and CSS look like for a typical program code snippet?

I'm going to assume that you have removed any font overrides from your CSS in the ebooks since they can and will keep font substitution from working.

As jackie_w asked, are you sending the books to your Kobo as epub or kepub?

In the librmsdk.so.0.0.1 yaml file, you can enable the Default ePub monospace font (Courier) patch which will then use your sideloaded monospaced file as the default. Alternate fonts will work but you may have to play games with the font names to fit into the maximum 7 characters for the font names.

I used to use a sideloaded font with CSS to use a monospaced font but the above patch allows to to simply refer to monospace/code in the CSS.

@font-face {
    font-family: monospace;
    font-weight: normal;
    font-style: normal;
    src: url('res:///fonts/normal/Dark Courier');
    } 
@font-face {
    font-family: monospace;
    font-weight: normal;
    font-style: italic;
    src: url('res:///fonts/italic/Dark Courier');
    } 
@font-face {
    font-family: monospace;
    font-weight: bold;
    font-style: normal;
    src: url('res:///fonts/bold/Dark Courier');
    } 
@font-face {
    font-family: monospace;
    font-weight: bold;
    font-style: italic;
    src: url('res:///fonts/bolditalic/Dark Courier');
    }

code {
    font-family: "Dark Courier", monospace;
    }
