Actually the formatter must return unicode object (because the cache system concatenate the returned string with other unicode strings). Thus i must convert my PNG image raw data into a unicode object. Then, when sending the result, the request encode it using config.charset (="utf-8"), and my PNG data are thus encoded in UTF-8...

Encoding HTML in UTF-8 is fine since the HTML code includes <meta http-equiv="Content-Type" content="text/html;charset=utf-8">. But there is no such meta-information for binary files like PNG or JPEG !
I guess the same problem will occur with any formatter that generates a binary file, including PDF.

I've put the patch here :

My formatter is very specific to my card design, so i fear it is of little interest...
