Addendum
Xara adds Font Awesome text symbols as a class .xr_sn. The n depends on the number of font and styles used and when you added the symbol
To get the exact class you need to examine xr_text.css to find exactly which class number (n) are being used for your symbols.
A quick way I to search the source code in the Preview (right-click > View source) and search for "xr_s" (no digit) and look for SPANs that only have a pattern like "&#nnnnn;" with no other text.
You can use this example CSS in the page head:
The number 2 above may be different your your design.<style> .xr_s2 {
color: red;
}
</style>
