#1182: utf8 egg silently accepts invalid byte sequences
-------------------------+--------------------------------------------------
  Reporter:  syn         |       Owner:  ashinn

 Component:  extensions  |     Version:  4.9.x  
Resolution:  invalid     |    Keywords:  utf8

Comment(by ashinn):

 Yes, a validation predicate is a long-standing todo.
 I met get around to it soon, patches are also welcome.

 It would in theory be possible to validate every input
 to every utf8 operation, but I have no intention of doing
 so, for performance reasons and because people may
 currently be using invalid utf8 in "safe" ways already.
