FYI -- see Sebastien's question below, posted on the IETF apps-discuss 
mailing list.

Is there a specification/interop problem with respect to header encoding 
in multipart/form-data?

Best regards, Julian

All,



There seems to be an issue with 2388 describing multipart/form-data. It
says that the field name (aka the name= parameter) has to be encoded
using 2047 when containing non-ascii characters. As I understand it, the
filename parameter itself is to be encoded with 2231, and 2047
specifically states that it is not to be used in parameters.



So thereís a clash between 2047 and 2388, which should probably be
addressed. In the mean-time, Iíd like to know if anyone has been known
to use 2047 for parameters?



Iíve quickly tested browser implementations, and they simply pass back
the UTF-8 code points Iíve provided in the markup, which I find very
surprising. How do people deal with such code-points in the headers?



Thanks,



Sebastien Lambla
