如何設定連字符的最小字元數？

Question

（與我的另一個問題相關這裡.）似乎音譯梵文的多語言連字符規則默認允許在單個字符後連字符。請參閱範例，ulūkādayaḥ第三行和第四行之間的單字僅在一個字元後用連字符連接。例如，我怎麼才能將其更改為兩個字元？

\documentclass[12pt]{article}

\usepackage{fontspec}
\usepackage{polyglossia}

\setdefaultlanguage{sanskrit}
\newfontfamily\sanskritfont{TeX Gyre Pagella}

\setotherlanguage{english} 
\newfontfamily\englishfont{TeX Gyre Pagella}

\begin{document}

asmadādiviśeṣaṇaśūnyasyārthasākṣātkāritvamātrasyaivendriyādhīnatvadarśanād anaikāntikatvam asambhavīti cet | yady evam arthasākṣātkāritvamātrasyendiryavadālokādhīnatvam upalabdham iti na santamase paśyeyur ulūkādayaḥ | atha vyabhicāradarśanād ālokasyāvyāpakatvam, vyabhicāraśaṅkayā tarhīndriyasyāpy avyāpakatvam | vyāptyā śaṅkā khaṇḍyata iti cet | śaṅkāsambhavād vyāptir evāsambhavinī yadi prathamata eva vyāptiḥ, vyabhicāro 'pi na dṛśyeta | 


\end{document}

編輯：我仍然不完全明白。我現在正在嘗試將兩端的最小可連字元減少為一個：

\documentclass[12pt]{article}

\usepackage{fontspec}
\usepackage{polyglossia}
\tracingparagraphs=1
\setdefaultlanguage{sanskrit}
\setotherlanguage{english}

\PolyglossiaSetup{sanskrit}{
  hyphenmins={1,1},
}

\newfontfamily\sanskritfont{TeX Gyre Pagella}
\newfontfamily\englishfont{TeX Gyre Pagella}

\begin{document}

anaikāntikatvam asambhavīti cet | yady evam arthasākṣātkāritvamātrasyendiryavadālokādhīnatvam upalabdham iti na santamase xx paśyeyur ulūkādayaḥ | atha vyabhicāradarśanād ālokasyāvyāpakatvam, vyabhicāraśaṅkayā tarhīndriyasyāpy avyāpakatvam | vyāptyā śaṅkā khaṇḍyata iti cet | śaṅkāsambhavād vyāptir evāsambhavinī yadi prathamata eva vyāptiḥ, vyabhicāro 'pi na dṛśyeta | 


\end{document}

並得到以下輸出：

我很驚訝它沒有用連字號來產生我所期望的過滿的 \hbox khaṇḍya-ta。

我可以看到它通常不想在最後一個音節之前連字符，為什麼會這樣呢？

Answer 1

你可以加

\PolyglossiaSetup{sanskrit}{
  hyphenmins={2,3},% default is {1,3}
}

\documentclass[12pt]{article}

\usepackage{fontspec}
\usepackage{polyglossia}

\setdefaultlanguage{sanskrit}
\setotherlanguage{english}

\PolyglossiaSetup{sanskrit}{
  hyphenmins={1,3},
}

\newfontfamily\sanskritfont{TeX Gyre Pagella}
\newfontfamily\englishfont{TeX Gyre Pagella}

Answer 2

這篇文章引發了github問題，他們因無法修復而關閉了。但隨後的線程確實提到了幾種解決方法：

1. \providehyphenmins{sanskrit}{11}提前隨時打電話\setdefaultlanguage{sanskrit}
2. 將巨集設定\sanskrithyphenmins為11（providecommand之前\setdefaultlanguage{sanskrit}、renewcommand之後）
3. 稱呼

\lefthyphenmin=1
\righthyphenmin=1

之後\begin{document}（\AtBeginDocument不起作用，etoolboxAfterEndPreamble會的）。 “但是任何語言變化都會被覆蓋。”

方法2的例子：

\documentclass{article}

\usepackage[width=4.4in]{geometry}
\usepackage{fontspec}
\usepackage{polyglossia}
\setdefaultlanguage{sanskrit}
\renewcommand*{\sanskrithyphenmins}{11}
\setotherlanguage{english}

\PolyglossiaSetup{sanskrit}{} % still necessary

\begin{document}
