I want to add ‘c++’ tag but ‘+’ sign is not permitted.
I found that c++ tag on the Stackoverflow.
Which tag is not permitted for tag in discourse?
And it is possible to use ‘c++’ tag in discourse?
Thank you

This is a complicated routing issue we have, we have deferred on this change for now, but I imagine we will get to it some day.
Sadly, no plans to add support in the near future.

If you’d like, assuming you haven’t already, you can use the file extension instead as a tag (#cpp), cpp is understood to be C++ anyway.
