Tags with special characters

[mortenbirkelund]

Describe the bug
Special characters in tags causes answer to assume incorrect urls. For instance a forward slash will be accepted in the tag, which obviously causes a problem in a url

To Reproduce
Steps to reproduce the behavior:

1. Create a tag with a forward slash "Something / something"
2. See that the url that answer uses for the tag is https://yourdomain/tags/Something-/-something
3. Try and visit this url, and you will get a 404

Expected behavior
I expected that answer will either not allow special characters when creating tag, or would url-encode before creating the url.

In response to this situation, we have made a repair in V1.2.1, and special characters will be escaped in 1.2.1. this version will be released soon.

In 1.2.1, the url will be displayed like this /tags/something-%2F-something.

While escaping works, it doesn't seem to match the prompt message.

@sy-records May be we need remove the prompt message.

We ignored the prompt message for editing the tag when modifying the condition. The latest news should be

The prompt message you marked should be consistent with the above. Maybe you can help us fix the prompt message!
