Hi, because nobody in der Localizer-Mailings list react and I thinks it could be a common problem with utf-8 in zope, I ask my question here also. I use Localizer 1.2.1 and I try out some things and all looks great. After testing Localizer my next plan was to switch from encoding ISO-8859-15 to utf-8 in Zope 2.10.3 but run into Problems when inserting text through a MessageCatalog (object of Localizer). Here is what I do in Zope: 1. I add "default-zpublisher-encoding utf-8" to my zope.conf and restart zope. 2. In ZMI I add the property "management_page_charset" and set it to "utf-8" 3. I add a new "DTML Document" and start editing. I check the encoding in my Browser and it switched to "unicode (utf-8)". Looks good. 4. I insert html-code and some russian chars for testing <html> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8"> </head> <body> ...russian chars... </body> </html> After Saving all looks great in ZMI and also in my webbrowser. 5. Now I add one line to use a MessageCatalog: <dtml-var "MessageCatalog('Hallo Welt!')"> After that, all of my utf-8-chars are broken in my webbrowser. I check browser-encoding and it is still utf-8. In ZMI my "DTML Document" looks good. This line must switch something in the output-encoding in the internal page-render (I don't know, how to better explain it). Is this an error in Localizer or in Zope or have I overlook a fault? Thanks Patrick
