The trouble with that is much of the UTF-8 out there is not valid. You don't 
want, for example, your html page to refuse to display at all because there's a 
couple invalid UTF-8 sequences in it. You don't want your text editor to refuse 
to load a file with invalid UTF-8 in it, either. You don't want your forms 
processor to summarily reject anything with invalid UTF-8 in it.

A better approach is to have the string processing be tolerant of invalid UTF-8.
