我正在使用pandoc
XeLaTeX 引擎。我遇到一个问题,某些字符周围的空间一边比另一边大。给出如下 markdown:
`X ≼ Y` // 3 spaces on the right
`X ≼ Y` // 2 spaces on the right
`X ≼ Y` // 1 space on the right
生成的乳胶(通过pandoc
)是:
\texttt{X\ ≼\ \ \ Y}
\texttt{X\ ≼\ \ Y}
\texttt{X\ ≼\ Y}
结果是:
请注意, 左侧的一个空格≼
大约等于 右侧的 3 个空格。此外,Y
在 之后使用该字符时,会使用错误的字体打印≼
。
可能是什么问题?是不是因为我用的是后备字体只针对这个单个字符,它会影响间距吗?
\usepackage{ucharclasses}
\newfontfamily{\fallbackfont}{FreeMono}
\newfontfamily{\mymainfont}{MyFont}
\setTransitionsForMathematics{\fallbackfont}{\mymainfont}
编辑包括整个 markdown 和生成的 LaTeX:
我的降价:

答案1
显然,在你的例子中,从 fallback 切换回来是混乱的,也就是说,它甚至\mymainfont
在≼
之内 \texttt
。这就是为什么你最终会得到不同长度的空间。
如果您只想要极少量的后备字符,我建议手动设置它们:
\documentclass{scrbook}
\usepackage{unicode-math}
\setmainfont{Merriweather}
\setmonofont{FreeMono}
\usepackage{newunicodechar}
\newfontfamily{\fallbackfont}{FreeMono}
\DeclareTextFontCommand\textfallback{\fallbackfont}
\newunicodechar{≼}{\textfallback{≼}}
\begin{document}
Test: \texttt{X\ ≼\ Y} test test
\texttt{X\ ≼\ \ \ Y}
\texttt{X\ ≼\ \ Y}
\texttt{X\ ≼\ Y}
X ≼ Y
