Per cent encoding in source URLs

[siwhitehouse]

Brief Description
A publisher uses per cent encoding to represent blank spaces in country names that appear in the URLs on their server
IATI Registry interprets these encodings and turns them into blank spaces. e.g. https://.../countrydata/iatiActivity_Bosnia%20and%20Herzegovina.xml becomes
https://.../countrydata/iatiActivity_Bosnia and Herzegovina.xml

This results in 404s in the Registry and risks breaking links in other tools

Severity

Steps to Reproduce
Create a publisher in Staging, host a file that includes per cent encoding to represent blank spaces in the URL.
