[SOLVED] How to replace spaces from parameters in Fandom's Wikitext?

How to replace spaces from parameters in Fandom's Wikitext?

I want to create an infobox template using Fandom's Wikitext that has data which links to Wikipedia. So, if someone uses the template like:

{{Person Infobox
| city=Los Angeles
}}

it would be display in the infobox as:
City: Los Angeles

I tried:

<infobox>
    <data source="city">
        <label>City</label>
        <format>[https://en.wikipedia.org/wiki/{{{city}}} {{{city}}}]</format>
    </data>
</infobox>

but the link breaks if the data has spaces.

How do I replace the spaces in {{{city}}} with %20 or is it impossible?

Solution

Fandom help forum is probably a better place for this type of questions, but there are two ways to do that:

urlencode

[https://en.wikipedia.org/wiki/{{urlencode:{{{city}}}|PATH}} {{{city}}}]

See https://www.mediawiki.org/wiki/Help:Magic_words

Interwiki link

In this method you use double brackets and a pipe like in internal links:

[[wikipedia:{{{city}}}|{{{city}}}]]
