Batch Geocoder API Developer's Guide

Request Encoding

Encode all query parameters in UTF-8, defining all special characters using a %FF hexadecimal representation. For example, "indelim=%5Ct" for "indelim=\t" and "indelim=%7C" for "indelim=|".

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