使用 LuaLaTeX 解决方案调整文档中的间距当我\label{}在数学环境中使用时，我遇到了这个神秘的错误：
(c:/texlive/2016/texmf-dist/tex/generic/oberdiek/se-pdfdoc.def
! Argument of \@providesfile has an extra }.
<inserted text>
\par
l.51 ...dblpnct{\hspace{0.08334em}}: PDFDocEncoding]
I've run across a `}' that doesn't seem to match anything.
For example, `\def\a#1{...}' and `\a}' would produce
this error. If you simply proceed now, the `\par' that
I've just inserted will cause me to report a runaway
argument that might be the root of the problem. But if
your `}' was spurious, just type `2' and it will go away.
Runaway argument?
{se-pdfdoc.def}{\@firstoftwo {\@hspacer }}\def \reserved@b {\@hspace \ETC.
! Paragraph ended before \@providesfile was complete.
<to be read again>
\par
l.51 ...dblpnct{\hspace{0.08334em}}: PDFDocEncoding]
I suspect you've forgotten a `}', causing me to apply this
control sequence to too much text. How can we recover?
My plan is to forget the whole thing and hope for the best.

您应该将 移出\hspace的定义中的 gsub，\dblpnct这样您就不必再与 的扩展作斗争了\hspace。然后您可以使用\NR@sanitize@labelname来清理标签名称。我夸大了插入的空间以检查是否有副作用。
