My last name has some weird spelling conventions that you may or may not be familiar with. The very short, not very precise version of it is that if it's next to my first name, the 'De' (the tussenvoegsel) should be lowercase, and otherwise in capitals. It is also alphabetised at the 'W', not at the 'D'.
Now, LaTeX struggles with this. So here's what I do when I cite my papers:
\begin{document}') I define a new command: DeclareRobustCommand{\DE}[3]{#2} and cite as usual. You can alter the argument (the #2) depending on what citation style you are using.
\bibliography as follows: \DeclareRobustCommand{\DE}[3]{#2}
author={\DE{Wynter}{De{de}}} Wynter, Adrian and ...
I have not modified the bib entries in this site because I'm not sure who's going to be checking this, but that's how I cite my papers (and any others that have tussenvoegsels in it).
I've just wasted a couple of your neurons with these cool facts™️. You're welcome.
