This could give an idea of what Perl folks do to get the grapheme feel 
like a unit of string:

You seriously don't want this kind of behind the scenes work taking

P.S. The text linked presents some incorrect "facts" about Unicode that 
I'm not to be held responsible for :) I do believe however that the 
general idea described is interesting and is worth trying out in 
addition to what we have in std.uni.
