Code Page in ICF

Each application must relate the representation of the texts in its response document (in the body of the document) to a suitable code page. The following example shows you how to convert a text into the UTF-8 code page and present it as part of a HTML page. For this purpose, the header field Content Type is set to ‘text/html' and the character set is set to utf-8. This tells the partner how to represent the HTML text.
