我想用几种不同的字体呈现相同的文本，但是当我执行以下操作时：
import settings;
import fontsize;
settings.tex="lualatex";
outformat="pdf";
size(9cm);
defaultpen(fontsize(10pt));
defaultpen(0.1);
texpreamble("\usepackage{fontspec}\setmainfont{Courier New}");
draw(scale(0.1) * texpath("text"));
texreset();
texpreamble("\usepackage{fontspec}\setmainfont{Arial}");
draw(shift(3, 0) * scale(0.1) * texpath("text"));
生成的图片仅包含用 Courier New 编写的文本。如果我将第 11 行和第 13 行更改为：
draw(scale(0.1) * texpath("text1"));
draw(shift(3, 0) * scale(0.1) * texpath("text2"));
文本渲染正确。这是怎么回事？我该如何用不同的字体渲染相同的文本？我在 Windows 7 上使用 TeX Live 2017。相关说明：当我尝试渲染带有标签的文本时，LuaLaTeX 会产生错误，如下所示：
texpreamble("\usepackage{fontspec}\setmainfont{Courier New}");
label("text", (0,0));
texreset();
texpreamble("\usepackage{fontspec}\setmainfont{Arial}");
label("text", (3,0));
错误：

...这是我对 xelatex 的 MWE，遵循说明这里。
\documentclass{standalone}
\usepackage{asymptote}
\begin{document}
\begin{asy}
import settings;
import fontsize;
//settings.tex="lualatex";
outformat="pdf";
size(9cm);
defaultpen(fontsize(10pt));
defaultpen(0.1);
texpreamble("\usepackage{fontspec}\setmainfont{Courier New}");
texpreamble("\newfontfamily\myfont{Arial}");
draw(scale(0.1) * texpath("text"));
draw(shift(3, 0) * scale(0.1) * texpath("{\myfont text}"));
\end{asy}
\end{document}
如果你编译
import settings;
import fontsize;
settings.tex="lualatex";
outformat="pdf";
size(9cm);
defaultpen(fontsize(10pt));
defaultpen(0.1);
texpreamble("\usepackage{fontspec}\setmainfont{Courier New}");
texpreamble("\newfontfamily\myfont{Arial}");
draw(scale(0.1) * texpath("text"));
draw(shift(3, 0) * scale(0.1) * texpath("{\myfont text}"));
使用asy -V，正如您所做的那样。
