I don't ! UTF16 is able to handle all charset and can be used directly with D2009 and up. Before D2009, the user will have to add code to encode their international characters in UTF8 and the component will have to have code to handle it properly. In the component code, you'll have conditional compilation for handling string properties which have a need for international charset. For example a filename in the FTP component. Assuming FTP protocol want UTF8 string, then when compiled with D2009 and up, the component will convert unicode string (UTF-16) to UTF-8 before sending down to the wire. When compiled with pre-D2009, the component will simply takes the string as an UTF-8 string and send it as is. At the application level, let's assume the application has a TEdit to enter a file name. With D2009 and up, there is nothing to do, just pas the text value (UTF-16 !) to the component. With pre-D2009, the application developer will need to use a unicode enabled TEdit (not provided with Delphi !), convert the text value to UTF-8 and feed the FTP component property with it. Isn't it too simple ?
