As of a couple of months ago, Netscape/Mozilla did so by default.
There is an obscure, undocumented configuration parameter that
can be placed in the configuration file to change that to use
2231 encoding, but (again, as of a couple of months ago) it did
not work:
1. 8-bit file names were first 2047-encoded, then that encoded via
the 2231 mechanism
2. instead of a single language tag, a language list was used under
some circumstances.
I think a bug report was submitted, but a quick search at bugzilla
today didn't show anything relevant.
With the obscure configuration parameter in place, Mozilla 1.2a
produced the following (which, as the filename is us-ascii, does not
show problem #1):
