使用空格对 biblatex 名称进行排序

Question

我希望“De Groote”排在“Deane”之前，但不知何故biblatex排序而言，它会占用名称中的空格。这会受到某个开关的影响吗？

这是一个 MWE。

\documentclass{article}

\begin{filecontents}{\jobname.bib}



@book{Deane92a,
        author = {Paul D. Deane},
        booktitle = {Grammar in Mind and Brain: {Explorations in Cognitive Syntax}},
        number = {2},
        publisher = {Mouton de Gruyter},
        series = {Cognitive Linguistics Research},
        sortname = {Paul Deane},
        title = {Grammar in Mind and Brain: {Explorations in Cognitive Syntax}},
        year = {1992}}


@proceedings{FG2008,
        address = {Stanford, CA},
        booktitle = {Proceedings of {FG 2008: The 13th Conference on Formal Grammar}},
        editor = {de Groote, Philippe},
        publisher = {CSLI Publications},
        title = {Proceedings of {FG 2008: The 13th conference on Formal Grammar}},
        year = {2008}}



\end{filecontents}

\usepackage[
        natbib=true,
%   style=langsci-unified,
        citestyle=langsci-unified,
        backend=biber,
]{biblatex}


\addbibresource{\jobname.bib}

\begin{document}
\cite{*}

\printbibliography
