I recommend trying to set the encoding in the web container's configuration (eg: server.xml).

Thanks for the answer. So Trinidad is fine, which is good news, but I have to find another explanation as why it fails on my app. If I'm not mistaking, the browser should make the conversion on-the-fly before putting the new content into the page. But it does dot, and I have  © characters, meaning that those are utf8 chars interpreted as windows-1252. About the reason that I am using win1252 instead of utf-8 : I'd be glad to hear that it's not totally "unavoidable". We're developping a new application that will come as a complement of our older ones. One prerequisite is to re-use some database tables (say, customers, cities/countries, and the likes). The database used is... Oracle 10 XE (yeah, I know, don't get me started), which has no i18n support, and only knows windows-1252. I'm not the Master of Charset Encoding, especially when it comes to databases, but I was told that in this special case, I cannot instruct the Oracle server that I'm a utf8-speaking client, so I have to use the default, which is windows-1252. I'd take ANY solution to this problem, as far as it doesn't break the compatibility with the other apps using the same database. If there's a way to have xmhHttpRequest responses correctly displayed as windows1252, then I'm fine. If I can instead keep utf8 and still use the existing databases as-is, it'll make my day :o) Again, thanks for answering me Regards, Cedric Durmont 2010/2/11 Andrew Robinson <[email protected]>: > According to the W3C specification, XML http responses should always > use UTF-8 encoding (requests too actually) > http://www.w3.org/TR/XMLHttpRequest/ > > "Authors are strongly encouraged to encode their resources using UTF-8" > > http://erik.eae.net/archives/2005/05/27/18.55.22/: > "UTF-8 is the standard encoding for XML files, so it MSXML probably > assumes that all files have that encoding if none is set." > > http://www.w3.org/TR/2006/WD-XMLHttpRequest-20060405/ > "responseText of type DOMString > If the readyState attribute has a value other than 3 (Receiving) or 4 > (Loaded), it must be the empty string.
