`\zugferd_startInvoiceSums:` produces text output

[SaculRennorb]

First of; thank you for creating basically the only package that can even create the attachments. I did however run into a few problems using it.

The only one I didn't manage to solve is this one:

using .\csname zugferd_startInvoiceSums:\endcsname. (within the ZUGFeRD environment) produces this random Omega and some white space (I added the dots to show the white space):

I'm using the version currently available on CTAN (0.8 2024-09-11) and I haven't tried using the code on the master branch directly. I'm also not going to, I'm just reporting this before I just slap some \color{white} on to it and call it a day. Everything else works just as expected, and I don't have the patience right now to dive deeper into why this might happen.

Hm… I tried to reconstruct and can not. Can I get more details and a full log? Would love to get a \listfiles included.

Oh, you are running on pdflatex without a T1 font encoding? Explains why I did not see it before, as it's a newline char which is expanded otherwhise to a space which will be stripped of in a tabular. I will remove it, but …

Writing files from pdflatex might have some side effects with unicode-chars. So maybe you would prefer using lualatex.

I can repro this with xelatex, can work on a reproduces if required :)

[TeXhackse]

In that case you probably want to check your font setup/encoding. This should not happen otherwhise. But I found the linebreak causing this as you can see in the commit above. Just am thinking about what's the best way to construct unit tests for this issue. But have an idea.

Here is a minimal repo case (could be more minimal but it should be good enough). No other packages, no special encoding. just basic latex.
