-| * Omnidex recommends use of the CHARACTER and C STRING datatypes rather than VARCHAR and CLOB due to the requirement of a length variable. ||
-=== National Character Datatypes ===
-Omnidex also provides partial support for National Character Datatypes (sometimes called
-Unicode datatypes or wide characters).  The Omnidex SQL Engine will process these
-datatypes, but the Omnidex Indexing Engine will only index the lower 8 bits of these
-datatypes.
-^ Datatype                  ^ Description                                                ^
