I presume this is due to mishandling of a wide character column or
something like that. You could add some debug statements in the
gdal/port/cpl_odbc.cpp code in an attempt to determine what column
type is coming back for the problem columns and see if that suggests

Debuging MS SQL related bugs isn't really all that convenient for me.
