I was just curious why anyone would use anything other than the ASCII
question mark as an ordinary question mark when writing in English in
a newsgroup.

The post had this:

0000520 61 72 63 68 28 29 20 20 ef bc 9f 0a
          a   r   c   h   (   )  sp  sp   o   <  us  nl

od is showing (ef bc 9f) as (o < us) but since they are not individual
characters anyway, never mind that. Google tells me (ef bc 9f) is
UTF-8 for U+FF1F FULLWIDTH QUESTION MARK, so now I basically have my
answer as to what it is, though still not as to why one would use it.

The ordinary question mark would look like this:

0000000 61 72 63 68 28 29 20 3f 0a
          a   r   c   h   (   )  sp   ?  nl
