Geocoder API Developer's Guide

Request Encoding

All query parameters in requests against Geocoder API resources require encoding in UTF-8. To represent any special characters, use the %FF hexadecimal representation. For example, "K%C3%B6ln" for "Köln".

White spaces can be replaced by the + sign or %20. In this guide, we use + for simplicity.

An example request for Köln, Germany:

When using HTML forms to submit queries to the service, use the accept-charset attribute to specify UTF-8 encoding instead of relying on the browser settings for parameter encoding:

<form action="
  geocode.xml" method="GET" accept-charset="UTF-8">
  <!—-  etc. -->
