Hi Alistair, I hope you find time to do your work.... more questions :)
Why should the IE client which is definitely reading/parsing as ISO-8859-15(i can see this in the IE menu bar), then post to the server converting the Euro to a questionmark . its rather stupid of IE isn't it, its definitely reading as ISO-8859-15 then posts anyway as ISO-8859-1 ? Could you explain in simple english, how the filter ensures that the request is in utf8 encoded. regards Ben p.s. greetings from germany. -----Urspr�ngliche Nachricht----- Von: Allistair Crossley [mailto:[EMAIL PROTECTED] Gesendet: Mittwoch, 1. September 2004 10:19 An: Tomcat Users List; [EMAIL PROTECTED] Betreff: RE: JSP/HTML Encoding The filter I sent you ensures that the "request" is encoded as UTF-8 which includes the euro character. When you are posting your forms with the euro character I believe your request is set to ISO-8859-1 and you lose the information, hence the ?. pageEncoding just sets the "response" encoding for the client and does not affect the other direction, i.e client => server. I am not sure if there is another setting where request character encoding can be set. Perhaps a more experienced Tomcat user knows this Cheers! > -----Original Message----- > From: Ben Bookey [mailto:[EMAIL PROTECTED] > Sent: 31 August 2004 17:06 > To: Allistair Crossley > Cc: Tomcat User List > Subject: AW: JSP/HTML Encoding > > > 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 ?
