Following this question, I would like to embolden specific references in my bibliography. The difference with the previous question is that I would like to use the abbrvnat bibliography style.
The proposed code, to put in the preamble (bellow), does not work when I use the abbrvnat style, while it does with the plain one.
\usepackage{xparse}
\ExplSyntaxOn
\clist_new:N \g_boldcite_list_clist
\cs_new:Npn \boldcite_checkkey:n #1
{
\clist_if_in:NnTF \g_boldcite_list_clist { #1 } { \bfseries } { \mdseries } \boldcite_bibitem:n {#1}
}
\cs_set_eq:NN \boldcite_bibitem:n \bibitem
\RenewDocumentCommand{\bibitem}{m}
{
\boldcite_checkkey:n { #1 }
}
\NewDocumentCommand{\boldreferences}{m}
{
\clist_gput_right:Nn \g_boldcite_list_clist { #1 }
}
\ExplSyntaxOff
Then by using \boldreferences{key1,key2}, the selected references become bold in the bibliography.

It seems that the above code changes a little the generated .aux file, and it depends on the style. The 'normal' .aux file (without using the custom code) looks like:
...
\bibcite{ref1}{{1}{year1}{{X et~al.}}{{authors}}}
\bibcite{ref2}{{2}{year2}{{Y et~al.}}{{authors}}}
\bibcite{ref3}{{3}{year3}{{Z et~al.}}{{authors}}}
...
Using the custom code with the plain style, I get the following:
...
\bibcite{ref1}{{1}{}{{}}{{}}}
\bibcite{ref2}{{2}{}{{}}{{}}}
\bibcite{ref3}{{3}{}{{}}{{}}}
...
Again with the custom code, and abbrvnat or apalike or (I think) all styles with that need author/year:
...
\bibcite{[}{{1}{}{{}}{{}}}
\bibcite{[}{{2}{}{{}}{{}}}
\bibcite{[}{{3}{}{{}}{{}}}
...
I suspect something related to Latex3 and some special character ([), but I have no idea how to solve it.
I am using natbib and xelatex.
