如何让 \textcite{} 在正文中的名字首字母和姓氏之间插入一个不间断空格？

假设我使用 biblatex，并引用了两位姓氏相同的作者的两篇论文，A. Smith (2019) 和 B. Smith (2020)。如果我使用，\textcite{Smith2020}它可能会编译为

Lorem ipsum dolor sit amet, consecteturB.

史密斯 (2020)adipiscing elit, sed do eiusmod

我怎样才能让它像下面这样编译？

Lorem ipsum dolor sit amet, consectetur

B.史密斯 (2020)adipiscing elit, sed do eiusmod

最安全的方法可能是

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[backend=biber, style=authoryear]{biblatex}

\newbibmacro*{name:giveni-family}[4]{%
  \usebibmacro{name:delim}{#2#3#1}%
  \usebibmacro{name:hook}{#2#3#1}%
  \mkbibcompletenamegivenfamily{%
    \ifdefvoid{#2}
      {}
      {\mkbibnamegiven{#2}\isdot\addnbspace}%
    \ifdefvoid{#3}
      {}
      {\mkbibnameprefix{#3}\isdot
       \ifprefchar
         {}
         {\ifuseprefix{\bibnamedelimc}{\bibnamedelimd}}}%
    \mkbibnamefamily{#1}\isdot
    \ifdefvoid{#4}{}{\bibnamedelimd\mkbibnamesuffix{#4}\isdot}}}

\DeclareNameFormat{labelname}{%
  \ifcase\value{uniquename}%
    \usebibmacro{name:family}
      {\namepartfamily}
      {\namepartgiven}
      {\namepartprefix}
      {\namepartsuffix}%
  \or
    \ifuseprefix
      {\usebibmacro{name:giveni-family}
        {\namepartfamily}
        {\namepartgiveni}
        {\namepartprefix}
        {\namepartsuffixi}}
      {\usebibmacro{name:giveni-family}
        {\namepartfamily}
        {\namepartgiveni}
        {\namepartprefixi}
        {\namepartsuffixi}}%
  \or
    \usebibmacro{name:given-family}
      {\namepartfamily}
      {\namepartgiven}
      {\namepartprefix}
      {\namepartsuffix}%
  \fi
  \usebibmacro{name:andothers}}

\begin{filecontents}{\jobname.bib}
