    Thanks for sharing this tip.

    Just don’t use random characters when there are appropriate Unicode characters like U+2665 ♥ available:
    <a href=”/” class=“icon” data-icon=“k”>Favourites</a>
    shold be
    <a href=”/” class=“icon” data-icon=“♥”>Favourites</a>.

    Using appropriate characters ensures that the desired symbols will be displayed (in some system font that contains a glyph for that particular symbol) even if the desired webfont is not loaded.

    Check the Unicode charts for symbols.
