First of all you using a (generated) icon font not the svg's directly. There are a lot of pros to use svg (https://css-tricks.com/icon-fonts-vs-svg/) over a icon font.
But for your question: I would say, generate icon classes like
.icon-chevron:before {
content: '\e801';
...
}
and then use this class in your markup
<div class="icon-chevron">
And if its about the unicode directly, just make sure that the same svg gets always the same unicode by generation.
