TypeWriter 字體對 Polyglossia 套件沒有影響

Question

使用 XeLaTeX 引擎，MWE1 與 fontspec 和 ucharclasses 套件配合良好。但是當我將fontspec改為polyglossia（MWE2）時，沒有TypeWriter字體效果。而且，英文文字的第一句不是Times New Roman字體。有什麼解決辦法嗎？

MWE1

\documentclass[11pt,a4paper]{article}
\usepackage{fontspec}
\newfontfamily\khmerfont[Script=Khmer,Scale=0.9]{Khmer OS}
\newfontfamily\khmerfonttt[Script=Khmer,Scale=0.9]{Khmer OS}
\newfontfamily\englishfont{Computer Modern Roman}
\usepackage{ucharclasses}
\setTransitionTo{Khmer}{\khmerfont}
\setTransitionFrom{Khmer}{\englishfont}
\usepackage{fancyvrb}
\begin{document}
\noindent What is wrong? តើមានអ្វីប្លែក? What is wrong? តើមានអ្វីប្លែក?
\begin{Verbatim}
What is wrong? តើមានអ្វីប្លែក? What is wrong? តើមានអ្វីប្លែក?
\end{Verbatim}
\end{document}

在這兩種情況下我都會得到錯誤的輸出。至少在英文文字中，它們涉及更多的字體系列，因此您需要更複雜的字體變更。試試這個：

\documentclass[11pt,a4paper]{article}
\usepackage{fontspec}
\usepackage{polyglossia}
\newfontfamily\khmerfont[Script=Khmer,Scale=0.9]{Khmer OS}
\setdefaultlanguage[numerals=khmer]{khmer}
\setotherlanguage{english}
\usepackage{ucharclasses}
\makeatletter
\setTransitionTo{Khmer}{%
 \global\let\orif@family\f@family
 \khmerfont}
\setTransitionFrom{Khmer}{%
 \fontfamily{\orif@family}\selectfont}
 \makeatother
\usepackage{fancyvrb}
\begin{document}
\noindent What is wrong? តើមានអ្វីប្លែក ? What is wrong? តើមានអ្វីប្លែក?
\begin{Verbatim}
What is wrong? តើមានអ្វីប្លែក? What is wrong? តើមានអ្វីប្លែក?
\end{Verbatim}
\end{document}

如果您有高棉語專用的 tt 字體，您可以為目前系列添加一些測試。
