 + 
 +=== 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.
