单词起始下标符号前的空格太小（仅限 LuaLaTeX）

Question

我\textsuperscript在单词开头使用，我注意到，如下图所示，前一个单词和上标符号之间的空格，如果收缩，与其他空间相比变得太小了。

\raisebox如果使用而不是 ，也会出现问题\textsuperscript。

编辑 quark67指出该问题仅发生在LuaLaTeX，而不发生在XeLaTeX。

现在有了 XeLaTeX（没问题）：

比字母大得多的符号F和负 \hspace （返回 Lua）

\newfontfamily\symbola{Symbola}[FakeBold=0.5]
\newcommand{\book}{\textsuperscript{\scalebox{1.2}{\symbola\char"1F4D6}}}

使用 XeLaTeX，书籍符号仍然存在间距问题。

使用 LuaLaTeX：

Answer 1

该\textsuperscript命令与问题无关。Times New Roman 中的字母“f”在其边界框的右侧突出很多：

TeX Gyre Termes 的图片如下

不幸的是，没有提供斜体校正（也许可以使用 LuaLaTeX 添加，这样\hspace{...}您就可以键入 而不是命令\/）。

\documentclass{article}
\usepackage[lmargin=2.5cm,rmargin=2.5cm,bmargin=2.5cm,tmargin=3.5cm]{geometry}
\usepackage{fontspec}
\usepackage{graphicx}

\setmainfont{Times New Roman}[
  SmallCapsFont=TeX Gyre Termes,
  SmallCapsFeatures={Letters=SmallCaps},
]
\newfontfamily\djvs[BoldFont={* Bold}]{DejaVu Sans}

\newcommand{\tech}{%
  \textsuperscript{%
    \scalebox{0.85}{%
      \djvs\bfseries\symbol{"2318}%
    }%
  }%
}
    
\NewDocumentCommand{\techlexAUX}{mmm}{%
  \tech\hspace{-0.1em}%
  \textit{#1}%
  \IfNoValueF{#2}{\textsubscript{\upshape\scshape #2}}%
  \IfNoValueF{#3}{ `#3'}%
}
\NewDocumentCommand{\techlex}{>{\SplitArgument{2}{,}}m}{\techlexAUX#1}
 
\begin{document}

I'm trying \techlex{arbre,n,tree}.

\bigskip
    
Similarly, if \techlex{attirement,n,attracting} 

Similarly, if\hspace{0.1em} \techlex{attirement,n,attracting} 

\end{document}

笔记

1. 我简化了命令。
2. \kern的定义中的似乎\tech没有必要。
3. 该符号应该靠近后面的斜体单词，而不是远离。
4. 我添加了对小型大写字母的支持，因为我的 Times New Roman 版本没有它们。
5. 我改成graphics：graphicx你不想要1993年的版本，是吗？

Answer 2

我被告知不要对最初的问题进行过多的编辑，因此这里只是简要回顾一下。egreg不过，不会比所说的多太多。

为了弥补糟糕的斜体校正或较大的符号，最好在命令里面添加一个空格，像这样：

 \newfontfamily\djvs[BoldFont={* Bold}]{DejaVu Sans}
 
    
\newcommand{\tech}{\textbf{\textsuperscript{\scalebox{0.85}{\djvs\char"2318}}}}
    
\NewDocumentCommand{\techlexAUX}{mmm}{\hspace{0.05em}\tech\textit{#1}\IfNoValueF{#2}{\textup{\textsubscript{\textsc{#2}}}}\IfNoValueF{#3}{ `#3'}}
\NewDocumentCommand{\techlex}{>{\SplitArgument{2}{,}}m}{\techlexAUX#1}
 
\NewDocumentCommand{\booklexAUX}{mmm}{\hspace{0.05em}\book\textit{#1}\IfNoValueF{#2}{\textup{\textsubscript{\textsc{#2}}}}\IfNoValueF{#3}{ `#3'}}
