Why doesn't the specific font awesome symbol work?

Question

css

sofuwa.ru/awesome for some reason, a specific character \f30b does not work, for example, another one next to it, it works. And on one site I saw it works, I did the same and it does not work. I tried to connect different libraries, Now the most common

<link href="https://use.fontawesome.com/releases/v5.0.13/css/all.css" rel="stylesheet">

I don't understand why at all, I tried anyway.

The icon category is not specified, this symbol is only in the solid version (fas).

<a href="#" class="fas fa-long-arrow-alt-right"></a>
