Hi Allistair +++ Many thanks for your help. +++
I apologise when I ask some stupid questions... :) 1) I am not exactly sure what the benefit is, of seeing if the client is posting a utf8 encoded response ? Surely, the server controls anyway what encoding the html pages are in so if i post with Latin9 then the client can either read it or not. I guess this filter is useful in the case that the client browser doesnt support the character encoding (something hopefully similar) and posts the request in another character-code. The filter can then be used to see if this is happening or not ? 2) I would assume that Tomcat( being java) would always use either utf8 or utf16 so making the necessity of setting a jvm tomcat property unnecessary ? regards Ben -----Urspr�ngliche Nachricht----- Von: Allistair Crossley [mailto:[EMAIL PROTECTED] Gesendet: Dienstag, 31.

Our databases are all Windows Cp1252 which also include the euro symbol. I also forgot to mention we put an explicit filter on all inbound requests that set the inbound encoding to utf-8.
