It is not possible to replace spaces with dashes in the channel name. However, it works the other way around.

Even after several attempts, the original value remains the same.

Steps to reproduce:

1. Allow special characters in channel name
2. Create a channel named "this is a test"
3. Try to rename the channel to "this-is-a-test"

As you can see it shows successful, but the channel name stays the same. Furthermore, there is still a mix up of 'name' and 'fname' in different parts of the UI which is a bit annoying when you allow special characters.

Expected behavior:

Channel should be renamed to "this-is-a-test".

Actual behavior:

It's not.
