# tex4ht produces quotation marks instead of German umlauts

A simple file with umlauts compiled using make4ht test "xhtml,charset=utf-8" " -cunihtf -utf8" shows question marks instead of German umlauts. Here the MWE test.tex:

\documentclass{article}
\usepackage[utf8]{inputenc} %Files are encoded using UTF-8
\usepackage[T1]{fontenc} %The text uses German umlauts
\begin{document}
A text with some „ÜÖÄüöäß“.
\end{document}


Output:

A text with some „�������“.


This seams to be a bug in the current MikTeX installation (is it a bug of tex4ht or MikTex?).

My current workaround was to copy the file unicode.4hf from C:\Program Files\MiKTeX 2.9\tex4ht\ht-fonts\unicode\charset to C:\Program Files\MiKTeX 2.9\tex4ht\ht-fonts\unicode\charset\uni which solved the problem.

• It might be Miktex issue, your code works for me in TeXLive. Note that you make4ht -u test is functionally equivalent to your command. – michal.h21 Aug 3 '16 at 12:55
• Imho it is the miktex bug you already found. sourceforge.net/p/miktex/bugs/2350 – Ulrike Fischer Aug 3 '16 at 12:59
• Michal, unfortunately usage of -u option with a more complex tex file and further tex4ht options such as "frames" leads to other problems (no output at all). I am currently trying to find out what the source of the problem is. – Mik Aug 3 '16 at 13:58
• that would be clearly bug in make4ht, please try to make an example. there is actually one difference with -u option: it uses -cmozhtf instead of -cunihtf – michal.h21 Aug 3 '16 at 14:29
• Mihal, I am sorry, the -u option works well - I was using a wrong config file. – Mik Aug 3 '16 at 14:41

As mentioned there, the current workaround is copying the file unicode.4hf from C:\Program Files\MiKTeX 2.9\tex4ht\ht-fonts\unicode\charset to C:\Program Files\MiKTeX 2.9\tex4ht\ht-fonts\unicode (or to C:\Program Files\MiKTeX 2.9\tex4ht\ht-fonts\unicode\charset\uni).
If using make4ht with the -u option (as suggested by Michal), make4ht calls tex4ht with -cmozhtf option. Then tex4ht is actually supposed to look for unicode.4hf in ht-fonts/mozilla/charset/ directory but fails to find it there. In this case one should copy unicode.4hf from C:\Program Files\MiKTeX 2.9\tex4ht\ht-fonts\mozilla\charset to C:\Program Files\MiKTeX 2.9\tex4ht\ht-fonts\mozilla.
• could you please post output from tex4ht command? I mean lines below: Make4ht: tex4ht -cunihtf -utf8 "test.dvi". I am interested in location of unicode.4hf which is listed here – michal.h21 Aug 3 '16 at 15:15
• ah, this is strange, it should be ht-fonts/mozilla/charset/unicode.4hf in your case, not unicode/charset/uni/unicode.4hf. It seems that tex4ht on Miktex can't find the correct file. – michal.h21 Aug 3 '16 at 15:38
• Yes. and as Ulrike mentioned in sourceforge.net/p/miktex/bugs/2350 without the workaround C:/Program Files/MiKTeX 2.9/tex4ht/ht-fonts/iso8859/1/charset/uni/unicode.4hf)is found instead. – Mik Aug 3 '16 at 15:44
