Geocoder API Developer's Guide

Request Encoding

All query parameters in requests against Geocoder API resources require encoding in UTF-8. To represent special characters, use the %FF hexadecimal representation.

For example, use searchtext 'K%C3%B6ln' to query for city 'Köln'.

White spaces can be replaced by the + sign or %20. In this guide, we use + for simplicity.
Note: This example uses a HERE API Key to authenticate your request. For information on other possible options, see Authentication Guide. For examples of how to use the other authentication options with the Geocoder API, see Authentication Examples.

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. -->
