Neither Oracle nor SQL Server offer any protection against unpaired 
surrogates in the data base, so surely the buffer at 
https://core.tcl.tk/tdbcodbc/artifact?udc=1&ln=786&name=6ce9986a10 must 
also be initialized with a zero background. With that done, the 
remaining issue is that unpaired high surrogates will be swallowed 
silently and unpaired low surrogates will be substituted with \uFFFD, 
leaving applications no way to deal with them. For example, it will 
become nearly impossible to write a TDBC application fo delete or repair 
the misencoded data in the database.

The same problem exists in dealing with the WIndows file system, as I 
mentioned in an earlier message.
