Multi-Byte Character Support

The ArcotID OTP Desktop Client supports UTF-8, which is the variable width 8-bit encoding format of the universal Unicode encoding scheme. However, to run the ArcotID OTP Desktop Client in the UTF-8 mode, the middleware applications that interact with the ArcotID OTP Desktop Client must also support UTF-8 in the provisioning protocol messages.

The ArcotID OTP Desktop Client does the URL encoding of the Unicode characters when it sends the provisioning request to middleware applications, for example, Authentication Flow Manager, and the application must respond with the correct response, as follows:

• The server must include charset=UTF-8 in the Content type header if the XML content is UTF-8 encoded.
• Use of encoding=UTF-8 attribute in the XML header is optional, the ArcotID OTP Desktop Client ignores this attribute.
• The UTF-8 encoding in the XML must be a true UTF-8 encoding. For example, %C3%A9 is two bytes and not six.
