In the HTML window, characters with diacritics are malformed in blockquotes

There is a small problem with the fonts in the HTML preview pane. In the blockquotes, some (not all) characters with diacritics are displayed in bold, although they shouldn't.

This happens only in blockquotes, not in normal text, and only with some characters (those with "hacek" diacritics, e.g. ě š č ř ž). The browser is Google Chrome 31.0.1650.63 on Ubuntu Linux. The same error can be seen on my Chromebook.

From what I've heard, similar errors appear on other websites when "Latin Extended" variant is not included in the webfont definition. But I don't understand webfonts enough to provide more detail. Also, is there a standard way to change fonts in the StackEdit's HTML preview pane?

UPDATE: When increasing zoom in the browser window, it seems the non-blockquote text is affected too and some characters with diacritics are VERY SLIGHTLY bolder than other characters (it's far less evident than in the blockquote text).

Yes, you can always copy/paste this in Settings->Extensions->UserCustom:

userCustom.onReady = function() {
    $('#preview-contents').css('font-family', 'sans-serif');
}

Great, thanks. Are all these UserCustom hooks documented somewhere?
