Correct, there's a lot of combinations with no pre-combined form. This 
should be no surprise given that you can apply any number of combining 
marks to any character.

	mythical 7 with an umlaut: 7̈
	mythical 7 with umlaut, ring above, and acute accent: 7̈̊́

I can't guaranty your news reader will display the above correctly, but 
it works as described in mine (Unison on Mac OS X). In fact, it should 
work in all Cocoa-based applications. This probably includes iOS-based 
devices too, but I haven't tested there.
