SOLVED : Suppress a wikipage with a ? in its name

Hello,

I have created a wikipage with a ? in its name.
Since then it is not possible to delete it nor to save it with gitlab buttons.
I am a beginner in GitLab and command line.
When I try to clone repository to edit it locally I obtain the following errors:

Cloning into ‘Sirius.wiki’…

You can inspect what was checked out with ‘git status’
and retry the checkout with ‘git checkout -f HEAD’

When I look in the sirius.wiki folder only two items have been loaded…
Is there a way to delete definitely all the wiki items?

Thanks

I have finally found a solution to my problem.
If you commit an empty project.wiki folder it delete all your wikipage.
In my point of view, it may be interesting to explain these details of local wiki modification on the gitlab wiki guide page for other people.

Have a nice day.
