[Question] Is it possible to change the vote icons using the Magazine panel?

I would like to replace the upvote and downvote icons in my magazine. Adding these CSS rules with the developer tools of my browser does exactly what I want:

.fa-arrow-up:before
{

content: "any fontawesome glyph";

}

.fa-arrow-down:before
{

content: "any fontawesome brand glyph";

    font-family: Font Awesome\ 6 Brands;
    font-weight: 400;
}

However, when I add this to the CSS section of the Magazine panel, the " symbols get replaced with ", breaking the vote icons entirely. Are there any other ways to change the vote icons using the Magazine panel (preferably without using JS)?
