As a Wikidata editor I want to be able to enter a value that contains a space character for [[ https://www.wikidata.org/wiki/Property:P8419 | Archive Of Our Own tag (P8419) ]] and have the URL to result to the entry of the value on https://archiveofourown.org/
**Problem:**
When I follow the link provided by [[ https://www.wikidata.org/wiki/Property:P8419 | Archive Of Our Own tag (P8419) ]], spaces in the value are replaced by "+" in the resulting URL and the link does not work.
**Example:**
1. Enter "Harry Potter" leads to https://archiveofourown.org/tags/Harry+Potter instead of https://archiveofourown.org/tags/Harry%20Potter (the resulting link does **not** work)
2. Enter "Harry%20Potter" leads to https://archiveofourown.org/tags/Harry%20Potter (resulting link does work)
3. Enter "Harry%20Potter" also sometimes leads to https://archiveofourown.org/tags/Harry%2520Potter (resulting link does **not** work)
**Acceptance criteria:**
Editor does not manually replace space character with %20 in entered value.
