Thank you for trying the newer version.
Oh, I see. I am not surprised if ctags cannot handle null chars in input because the internal of ctags highly depends on C strings, byte sequences terminated with '\0'.
Ideally, this should be fixed, but we do not have enough time to fix it.

I will change the title of this issue.
from issues-we-will-not-fix-in-soon.
I have updated to Universal Ctags 6.1. and used your parameters (that all identical to mines) , with my file and there was still the missalignment.
When using the simplified version of the docu (as I pasted it before ) it works (providing {mgroup=1}).
The issue is that my files are generated by a bash script that appends contents with >> , somehow adding the null terminator character in between those topics.
This file full of null-terminator characters seems to mess Universal Ctags engine and end up missbehaving in the way I showed in my first post.
I will just pre-process the files to delete those null-terminator bytes, but should you want to check on the issue (don't know if you consider it as an issue or a bug) , I attach my documentation file so you can check what I said.
(I dont know why is not letting me attach text-files through github attachments so I use google.drive)
