I am trying to compile the weekly mathematica newsletter I get.
This time, I must have added something that tex4ht does not like
from the email I got from stackexchange.

When I compile the file using the same command I use all the time,
now it gives

Output written on content_all.dvi (988 pages, 7920264 bytes).
Transcript written on content_all.log.
[INFO]    make4ht-lib: executing: tex4ht  -cunihtf "content_all.dvi"
--- warning --- Too many characters (> 500) for map line: `l'
Then later it gives

Execute script `content_all.lg'

[INFO]    make4ht-lib: executing: t4ht  -utf8 "content_all.dvi"
--- error ---

t4ht.c (2018-07-04-14:25 kpathsea)
t4ht -utf8

[FATAL]   make4ht-lib: Fatal error. Command t4ht returned exit code 1


This file (called content_all.tex) compiles with no problem using
lualatex. (with the normal warnings, etc...)

Since tex4ht does not say where the line it is not happy with,
and what exactly is wrong. I am not sure why it giving this error

The command I used is

make4ht --shell-escape -ulm default -a debug -e ./new.mk4
       -c ./nma_mathjax.cfg content_all.tex
       "mathjax,htm,fn-in,3,notoc*,p-width,charset=utf-8"  " -cunihtf -utf8"

Could someone please see if they can reproduce this error?

I put zip file with all the content needed to compile it. After unzipping
the file, it will create folder called content_all/

Issuing the above command inside this folder will show the error.
The above command is also given in a text file inside the folder
called command.tex

Here is the zip file on my site:


Using TL 2020 on Ubuntu.

>which tex4ht

>make4ht --version
make4ht version v0.3f

ps. last week news letter compiled OK. Here is the result


So it is something in this week content which made tex4ht starts giving
errors. May be capacity issue?

Thanks for any suggestions
