我喜欢 提供的字体\usepackage{bera}。但在 tex4ht 中使用它时，它似乎会因为某种原因从某些单词中删除一些字母。在此示例中，它不喜欢这些f字母，并将其从所有单词中删除。
是否可以在 tex4ht 中实现此功能？以下是 MWE
\documentclass[11pt]{article}%
\usepackage{bera}
\usepackage[T1]{fontenc}
\begin{document}
term by term differentiation is justified here
\end{document}
lualatex foo.tex给出
但 make4ht -u foo.tex给予
我也试过
\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}
但结果是一样的。
是否需要一些技巧才能使其在 tex4ht 中工作，或者它根本不受支持？
在 Linux 上使用 texlive 2017。我仅使用lualatex它编译为 PDF，并使用使用make4ht -u它编译为 HTML。PDF 没问题，问题仅在于 HTML。

没有Bera字体的支持文件tex4ht，因此可能缺少特殊字符，例如您遇到的ff和fi连字符。您可以将以下文件添加到文档目录中：
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;
这些文件支持斜体和粗体变体。您还可以使用该选项LuaTeX作为编译器。make4ht-l
结果似乎是正确的：
