将 tex4ht 与该包结合使用时igo会出现一些错误消息。该igo包可在 上找到CTAN。

第 2 步：运行latex生成test1.tex所需的tfm和pk文件。
%% test1.tex
\documentclass{article}
\font\mybl=igobl10
\font\mywh=igowh10
\begin{document}
{\mybl \char0 \char1}
{\mywh \char2 \char3}
\end{document}
即正常工作。
下一步是测试pdflatex test2.tex：
%% test2.tex
\documentclass{article}
\input showfonts.4ht
\begin{document}
\showfonts
{igobl10}
{igowh10}
{}
\end{document}
PDF 文件显示正确的字形。有错误消息，表示缺少某些字符，例如Missing character: There is no h in font igobl10!；但这是意料之中的。
第 4 步：然后我运行，make4ht -m draft test1.tex 收到错误消息
--- warning --- Couldn't find font `igowh10.htf' (char codes: 0--9)`
我生成了htf文件igobl10.htf并igowh10.htf输入

TeX我将这些文件存储在与文件相同的目录中
现在运行make4ht -m draft test1.tex我收到错误消息

这与其他错误消息略有不同。
问题：我在这里做错了什么？
答案1
您的.htf文件是正确的，除了它们包含左单引号字符而不是直引号，并且第一个字符之前也不应有空格。此问题是由TeX4ht 文档，其中包含错误的引号。我已在 TeX4ht 源中修复了这个问题，因此希望它也能很快在网络上修复。
