How do I specify the character encoding for the parameters in the query string?

The query string of requests contains only ASCII characters. Other characters are encoded using the %XX notation, where XX is the character code for a given character encoding. For example, the character LATIN CAPITAL LETTER A WITH GRAVE 'À' would be represented as %C3%80 using the utf-8 encoding or %C0 using iso-8859-1.

NeoLoad uses 'UTF-8 by default as specified by the RFC 3986. Nevertheless, the server may expect a different encoding, typically iso-8859-1. The encoding used by NeoLoad may be changed in the <NeoLoad>/conf/Controller.properties file by editing (or creating) the [Runtime]http.querystring.encoding=UTF-8 key.
