bidi 包中的 extrafootnotefeatures 选项破坏了 KOMAScript \deffootnote

Question

我正在使用 KOMAScript 类scrartcl来排版包含英语和阿拉伯语的学术文章。对于脚注格式，我使用\deffootnote。

对于包含阿拉伯语文本的脚注，页边距很奇怪。此问题已通过软件包选项修复extrafootnotefeatures（bidi请参阅这个问题）。但是，这会破坏使用 所做的更改\deffootnote。

不带extrafootnotefeatures（左），带extrafootnotefeatures（右）

有没有办法获得正确的双向脚注，同时保留更改脚注格式的可能性？

下面是一个最小的工作示例。

\documentclass[english,a4paper]{scrartcl}
\usepackage{unicode-math}
\defaultfontfeatures{Scale=MatchLowercase}
\defaultfontfeatures[\rmfamily]{Ligatures=TeX,Scale=1}
\setmainfont[]{Charis SIL}
\setsansfont[]{Charis SIL Compact}
%% languages/scripts
\newfontfamily\arabicfont[Script=Arabic]{Scheherazade}
\PassOptionsToPackage{extrafootnotefeatures}{bidi}
\usepackage{polyglossia}
\setmainlanguage{english}
\setotherlanguage{arabic}

%% Footnotes (load after polyglossia!)
\deffootnote{\leftmargin}{1em}{%
\makebox[\leftmargin][l]{\thefootnotemark}%
}

% Restore original footnote rule
\makeatletter
\def\footnoterule{\left@footnoterule}
\makeatother

\begin{document}
%% No additional space between sentences
\frenchspacing

Answer 1

我想我误导了你最后一个问题！

糟糕的渲染是由阿拉伯语文本周围的空行造成的。如果删除它，那么即使没有 选项，它也可以正常工作bidi。extrafootnotefeatures然后您可以使用\deffootnote而不会产生副作用，以及删除 hack 以保持正常的脚注规则：

\usepackage{fontspec}
\defaultfontfeatures{Scale=MatchLowercase}
\defaultfontfeatures[\rmfamily]{Ligatures=TeX,Scale=1}
\setmainfont{Noto Serif}
\setsansfont{Noto Sans}
\newfontfamily\arabicfont[Script=Arabic]{Amiri}
\usepackage{polyglossia}
\setmainlanguage{english}

\deffootnote{\leftmargin}{1em}{\makebox[\leftmargin][l]{\thefootnotemark}}
