8389	"""Add names from Wikipedia"" WP-API-calls 'titles'-attribute are malformed since not urlencoded"	jjaf.de	simon04	"== Problem ==
Most of the calls of ""Add names from Wikipedia"" give a plugin-error, since WP-API returns `HTTP/1.0 400 Bad Request` for calls like:
{{{
GET /w/api.php?action=query&prop=langlinks&titles=St. John's, Antigua and Barbuda&lllimit=500&format=xml HTTP/1.1
User-Agent: Java/1.7.0_11
Host: en.wikipedia.org
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive
}}}
== Cause ==
The problem is, that the `wikipedia`-value wich ends up in `titles` is not urlencoded.
== Workaround ==
Workaround is to //temporarily// set an urlencoded `wikipedia=en:St._John's%2C_Antigua_and_Barbuda` copied from the browser-location.
== stackdump ==
