Full stops in folder names

Hi Again,

I think perhaps there is a bug here (or perhaps the docs are not up to date?).

On this page it says that periods should be removed:
https://javadoc.onehippo.org/11.0/hippo-repository/org/hippoecm/repository/api/doc-files/encoding.html

If I create a folder and type the name as:
this,is.aproblem/%name
… then the url name is:
thisis.aproblem-name

So the comma, slash and percent are all handled as specified in the javadoc but the period is not. Am I right that this is a bug? We are on version 12.5.1

Thanks!

David
