How to enable kinds for C++ in universal ctags from the command line

Question

I cannot seem to toggle any of the C++ kinds for universal ctags on the command line.

How do I get all kinds that are not enabled to be enabled?

I have run:

> ctags -R --kinds-c++=ADLNUZcdefghlmnpstuvxz .*

In an attempt to enable all C++ kinds in universal ctags.

However when I check to see if they are enabled, I get:

> ctags --list-kinds-full=c++

An asterisk is for enabling all the kinds:

$ ctags --options=NONE --kinds-c++='*' --list-kinds-full=c++
