The main problem with special Unicode characters, as I see it, is that it is 
no longer possible to distinguish characters unambiguously just by looking 
at them. Apart from questions of maintainability, this is also a potential 
security problem: it enables an attacker to slip in malicious code simply by 
importing a module whose name looks like a well known safe module. In a big 
and complex piece of software, such an attack might not be spotted for some
