LuaLaTeX 的 fontspec 使用 Arial Narrow，而 XeLaTeX 是正确的

LuaLaTeX 的 fontspec 使用 Arial Narrow，而 XeLaTeX 是正确的

我目前正在处理一个文档，该文档是在多台计算机上编辑的，两台计算机都运行 Windows 10。在这两种情况下，我都使用 Miktex (x64)。但是，当我尝试编译以下 MWE 时，其中一台机器上出现了问题：

\documentclass{book}  
\usepackage{fontspec}
\setmainfont{Arial}  
\usepackage{lipsum}   
\begin{document}
    \lipsum[1-5]
\end{document}

使用 XeLaTeX，PDF 看起来符合预期，Arial 显示为嵌入字体。但是，当我尝试使用 Lualatex 时，PDF 实际上使用的是字体的窄版本。

Xelatex 的输出如下：

.................................................
. fontspec info: "defining-font"
. 
. Font family 'Arial(0)' created for font 'Arial' with options
. [Ligatures=TeX].
. 
. This font family consists of the following NFSS series/shapes:

Lualatex 的输出是：

.................................................
. fontspec info: "defining-font"
. 
. Font family 'Arial(0)' created for font 'Arial' with options
. [Ligatures=TeX].
. 
. This font family consists of the following NFSS series/shapes:

我怀疑 Lualatex 实际上默认使用的是窄字体，而不是常规字体。运行luaotfload-tool --find="Arial"后输出如下

luaotfload | resolve : Font "Arial" found!
luaotfload | resolve : Resolved file name "c:/windows/fonts/arialn.ttf

在我看来，查找实际上是错误的。我尝试使用cache=purge、force和flush-lookup选项，但无济于事。有没有办法可以手动修改查找以指向正确的文件？

这可以提供帮助，直到问题被修复并上传到发行版。

\documentclass{book}  
\usepackage{fontspec}
\setmainfont{arial}[ %Need such long loading because of luaotfload issue
    Extension = .ttf,
    UprightFont = *,
    BoldFont = *bd,
    ItalicFont = *i,
    BoldItalicFont = *bi]
\newfontfamily\cyrillicfont{arial}[ %for Cyrillic users
    Extension = .ttf ,
    UprightFont = *,
    BoldFont = *bd,
    ItalicFont = *i,
    BoldItalicFont = *bi]
\usepackage{lipsum}   
\begin{document}
    \lipsum[1-5]
\end{document}

Idea 可用于受影响的字体。可以检查

luaotfload-tool --find="Arial"

指向arialn.ttf哪个是 Arial Narrow，

luaotfload-tool --find="DejaVuSerif"

指向dejavuserifcondensed.ttf的是DejaVuSerifCondensed。

问题至少是一个月大。
