使用 Arial Narrow 和 LuaLaTeX 的 fontspec，而 XeLaTeX 才是正確的

使用 Arial Narrow 和 LuaLaTeX 的 fontspec，而 XeLaTeX 才是正確的

我目前正在處理一個在多台機器上編輯的文檔，兩台機器都運行 Windows 10。然而，當我嘗試編譯以下 MWE 時，一台機器上出現了問題：

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

使用 XeLaTeX，PDF 看起來符合預期，Arial 顯示為嵌入字體。然而，當我嘗試使用 Lualatex 時，PDF 實際上使用的是該字體的窄變體。

Xelatex 的輸出如下：

.................................................
. 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 的輸出是：

.................................................
. 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:

. - 'bold small caps'  (bx/sc) with NFSS spec.: - 'italic' (m/it) with NFSS

我懷疑 Lualatex 實際上預設為窄字體而不是常規字體。運行luaotfload-tool --find="Arial"給出以下輸出

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

在我看來，查找實際上是錯誤的。我嘗試使用cache=purge、force和flush-lookup選項，但無濟於事。有沒有辦法可以手動修改查找以指向正確的文件？

這可以幫助解決問題並將其上傳到發行版。

\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 可用於受影響的字體。可以查一查

luaotfload-tool --find="Arial"

指arialn.ttfArial Narrow 和

luaotfload-tool --find="DejaVuSerif"

指向dejavuserifcondensed.ttfDejaVuSerifCondensed。

問題至少是一個月大。
