我使用了另一個問題中的以下範例：
（XeLaTeX、Texlipse、polyglossia 德語問題）
%!TEX TS-program = xelatex
%!TEX encoding = UTF-8 Unicode
\documentclass[a4paper]{scrartcl}
\usepackage{xltxtra}
\usepackage{polyglossia}
\setdefaultlanguage{german}
\begin{document}
\begin{figure}
\centering
Test Test Test Test \TeX\ \XeTeX
\caption{Eine Abbildung}
\end{figure}
\end{document}
XeLaTex 產生以下錯誤代碼：
Package polyglossia Warning: \setlocalhyphenmin useless for unknown language ge
rman on input line 6.
Package polyglossia Warning: No hyphenation patterns were loaded for `ngerman'
(polyglossia) I will use \language=\l@nohyphenation instead on i
nput line 68.
! Undefined control sequence.
<argument> \xpg@nopatterns {ngerman}\adddialect
\l@ngerman \l@nohyphenation
l.68 ...man}{spelling,latesthyphen,script,variant}
早些時候它起作用了，但我不記得什麼時候了。
我在 Windows 10 x64 上使用 MikTeX。我剛剛又重新安裝了MikTeX，因為我懷疑TeX安裝錯誤導致的錯誤。
有任何想法嗎？

如果我使用命令 -q 編譯 XeLaTex 來抑制警告，我會得到一個看起來幾乎符合預期的 PDF 檔案。不幸的是，它在文件的開頭包含額外的字元。
不同的文檔編譯後結果是一樣的。除了附加字元之外，輸出是完美的。總是這個：ÿ
這些字元僅出現在多頁文件的第一頁。
