utfsym 与 XeLaTeX

更新

2022/04/17发布的新版本utfsym.sty适用于所有引擎。

为什么我们不能使用该utfsym软件包中的 XeLaTeX？有什么方法可以解决这个问题吗？以下是一个最小的工作示例。

\documentclass{article}
\usepackage{utfsym}

\begin{document}
\usym{2680} Many
\end{document}

此外，我知道一种调用某些特定符号的解决方案，该符号允许使用 XeLaTeX 或 LulaLaTeX：如果我们想调用编码为的符号abcd，我们只需要找到abcd.tikz文件在包裹里并将文件中的代码复制abcd.tikz到下面的空白处。

\usepackage{tikz}
\makeatletter
\newcommand{\heart}{\mathord{%
\resizebox{!}{\fontcharht\font`M}{%

}%
}%
}%
\makeatother

例如，如果我们要调用编码为的符号2665，那么我们将获得如下代码和输出。

\documentclass{article}

\usepackage{tikz}
\makeatletter
\newcommand{\heart}{\mathord{%
\resizebox{!}{\fontcharht\font`M}{%
\begin{tikzpicture}[y=0.80pt, x=0.80pt, yscale=-1.000000, xscale=1.000000, inner sep=0pt, outer sep=0pt]

但它似乎有点复杂，有没有什么简单的解决方案来调用一些特定的符号？

答案1

ufsym是一个似乎使用多个

 \DeclareUnicodeCharacter

将 Unicode 代码点映射到使用适合 pdftex 的 tikz 绘制的字符，在 xetex 或 luatex 中不需要，因为它们可以使用 Unicode Opentype 字体直接排版 Unicode 代码点。

在此处输入图片描述

\documentclass{article}

\usepackage{fontspec}
\setmainfont{DejaVu Sans}

\begin{document}

\symbol{"2680} Many ⚀ Many
\end{document}

如果你想要这些字符的 tikz 版本而不是真正的字体，即使使用 xetex，你也可以隐藏inputenc \DeclareUnicodeCharacter

在此处输入图片描述

\documentclass{article}

% hide inputenc commands
\makeatletter
\def\DeclareUnicodeCharacter#1#2{}
\makeatother

\usepackage{utfsym}

\begin{document}

\usym{2680} Many 
\end{document}

更新

2022/04/17发布的新版本utfsym.sty适用于所有引擎。

旧答案

utfsym与 XeLaTeX 或 LuaLaTeX 配合使用会很容易。

文件xutfsym.sty

文件已被剪切，但的修改utfsym.sty很简单：只需将第一部分更改为\DeclareUnicodeCharacter以下内容，并将所有出现的更改\DeclareUnicodeCharacter为\xutfsym@declare。

\NeedsTeXFormat{LaTeX2e}[1994/06/01]
\ProvidesPackage{xutfsym}[2022/04/16 Use TikZ to support icons from Unicode blocks ]
%% developed for use in package 'schule' 2016 by Daniel Spittank
%% this package is public domain, CC0
%% modified to work with (Xe|Lua)LaTeX (egreg)

%% - needs ut8 as input encoding
%% - TikZ paths are extracted from Symbola.ttf public domain font by George Douros,
%%   see: http://users.teilar.gr/~g1951d/
%% - supports direct use of unicode symbols
%% - supports textcolor
%% - supports fontsizes
%% - supported Blocks:
%%   - Miscellaneous Symbols and Arrows (2600-26FF)
%%   - Dingbats (2700-27BF)

\RequirePackage{xcolor}
\RequirePackage{tikz}
\RequirePackage{graphicx}
\RequirePackage{iftex}

%% command for symbol usage \usym{unicode number}
\newcommand{\usym}[1]{\resizebox{!}{\fontcharht\font`M}{\input{usym#1.tikz}}}

%% command for symbol usage as a picture, scaling by height
%% \usymH{unicode number}{height}
\newcommand{\usymH}[2]{\resizebox{!}{#2}{\input{usym#1.tikz}}}

%% command for symbol usage as a picture, scaling by width
%% \usymW{unicode number}{width}
\newcommand{\usymW}[2]{\resizebox{#2}{!}{\input{usym#1.tikz}}}

\iftutex
  % unicode engine
  \def\xutfsym@declare#1#2{%
    \begingroup\lccode`~="#1\lowercase{\endgroup\protected\def~}{#2}%
    \catcode"#1=\active
  }%
\else
  \let\xutfsym@declare\DeclareUnicodeCharacter
\fi

%% direct unicode support
\xutfsym@declare{1F000}{\usym{1F000}}
\xutfsym@declare{1F001}{\usym{1F001}}
% many other similar lines where the original
% file has \DeclareUnicodeCharacter
% I had to cut because of size limit in answers
% Up to the following one
\xutfsym@declare{27BF}{\usym{27BF}}

\endinput

测试

pdflatex现在，您可以尝试使用或来输入以下文件xelatex。

\documentclass{article}
\usepackage{xutfsym}

\begin{document}
