我喜歡 提供的字體\usepackage{bera}。但是當在 tex4ht 中使用它時，似乎由於某種原因從某些單字中刪除了一些字母。在此範例中，它不喜歡這些f字母並將其從所有單字中刪除。
可以在 tex4ht 中實現此功能嗎？這裡是MWE
\documentclass[11pt]{article}%
\usepackage{bera}
\usepackage[T1]{fontenc}
\begin{document}
term by term differentiation is justified here
\end{document}
lualatex foo.tex給出
但 make4ht -u foo.tex給出
我也嘗試過
\documentclass[11pt]{article}%
\usepackage{bera}
\ifdefined\HCode
\usepackage[utf8]{luainputenc}
\else
\usepackage[T1]{fontenc}
\fi
\begin{document}
term by term differentiation is justified here
\end{document}
但結果相同。
是否需要一種技巧才能在 tex4ht 中實現此功能，或者根本不支援它？
在 Linux 上使用 texlive 2017。我僅用於lualatex編譯為 PDF，並用於make4ht -u編譯為 HTML。 PDF 沒問題，問題只出在 HTML 中。

Bera中的字體沒有支援文件tex4ht，因此可能會丟失特殊字符，例如您的情況中的ff和fi連字。您可以將以下文件新增至文件所在的目錄：
fveb8r.htf：
.pcrro8r
htfcss: fveb8r font-weight: bold;
fvero8r.htf：
.pcrro8r
htfcss: fvero8r font-style: italic;
fver8r.htf：
.pcrro8r
fver8t.htf：
.lm-ec
fveb8t.htf：
.lm-ec
htfcss: fveb8t font-weight: bold;
fvero8t.htf：
.lm-ec
htfcss: fvero8t font-style: italic;
這些文件支援斜體和粗體變體。您也可以將LuaTeX其用作編譯器來make4ht使用該-l選項。
結果似乎是正確的：
