New Diagnostic Code Requested

In our next release of SiteSearch, we will be supporting the explicit
negotiation of characterset.  Specifically, we will allow the client to
negotiate the use of UTF-8 in searches.  With that comes the requirement
that we convert the UTF-8 query into the correct characterset for the
database being searched.  We need a diagnostic when the query includes
characters that do not translate into the target characterset.  The addinfo
field will contain the character (in the negotiated characterset) that could
not be translated.

We recommend a practice to other implementors of not ignoring illegal
characters.  Profiles are currently asking us to not ignore or misinterpret
attributes and I suspect that they will eventually ask us to treat the
user's query terms with as much respect.
