</span>There are two problems:<br>
<br>
1. Macros with Unicode names are supported only by Unicode engines, ie.<br>
XeTeX and LuaTeX. mk4ht oolatex is 8-bit pdflatex, so it can't really<br>
support it.<br>
<br>
2. utf2ent converts all Unicode characters to entities, including your<br>
command, so you end with something like '\\entity{1589}' in your code.<br>
<br>
3. $\langle$ and $\rangle$ produces wrong mathml code, see<br>
<br>
<a href="https://puszcza.gnu.org.ua/bugs/?278" rel="noreferrer" target="_blank">https://puszcza.gnu.org.ua/bugs/?278</a><br>
<br>
ODT format uses mathml, so it may produce invalid file.<br>
<br>
Now what can be done:<br>
<br>
You need to use Unicode engine. That means LuaTeX at the moment, as<br>
XeTeX support is broken in tex4ht at the moment. Fortunately, you can<br>
use XeTeX to produce the PDF and only modify some macros for tex4ht.<br>
<br>
With LuaTeX, it is possible to keep Unicode characters without need to<br>
call external scripts to convert them to Unicode entities. See<br>
<br>
<a href="http://michal-h21.github.io/samples/helpers4ht/fontspec.html" rel="noreferrer" target="_blank">http://michal-h21.github.io/samples/helpers4ht/fontspec.html</a><br>
<br>
for more details. I've modified your file to use alternative4ht and to<br>
fix the problem with angles. Two new macros are introduced: extlangle<br>
and extrangle, which are redefined in the config file to use XML<br>
entities directly, instead of math mode.<br>
<br>
I've also found a problem that the angles are wrongly swapped in the ODT<br>
and HTML, probably it is because they use the BIDI algorithm, so they<br>
don't expect that they are swapped by the user already (you use<br>
\rangle#1\langle). I've redefined the commands for angles in the config<br>
file to use the opposite side than should be used according to the name,<br>
so they are rendered correctly.<br>
<br>
The last problem is that mk4ht doesn't support LuaTeX, so you need to<br>
use different way to compile the document. You can use:<br>
<br>
make4ht -ulm draft -c hello.cfg main.tex "xhtml,ooffice" "ooffice/!<br>
-cmozhtf -utf8" " -cooxtpipes -coo"<br>
<br>
(it might be best to save it as a script, as it is not really human<br>
friendly command call :)<br>
<br>
Modified main.tex and hello.cfg are attached. main.tex can be compiled<br>
with xelatex to PDF, all needed changes for tex4ht are in the hello.cfg<br>
file.<br>
<br>
Best regards,<br>
