2047 in 2388: encoded words in multipart/form-data

["Sebastien Lambla" <[e-mail]>]

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 there's a clash between 2047 and 2388, which should probably be
addressed. In the mean-time, I'd like to know if anyone has been known to
use 2047 for parameters?

 

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

 

Thanks,
