I am using multiple url links in my bib source file and at the same time I would like to replace them with link symbol (e.g., \faLink from fontawesome5 in my example).
I insert the character directly in a \DeclareFieldFormat directive, based on question 304569. But this solution has an effect that all links are taken as one.
The \renewbibmacro*{url} to avoid the issue that biblatex converts the space separator between urls to "%20" before it reaches the code, Therefore I use the command to redefine the url bibmacro to use urlraw instead of url.
I need to somehow take link per link and replace them with own link symbols (\falink). Some bib entries have only one or link is missing. The code for handling multiple urls is taken from answer 57865.
