No, rather than the error check was on by default. Some people want it off as the default.
As far as Unicode strings are concerned, the question is a little different. Is it well defined behavior to create a string that does not meet the Unicode invariants? If so, can ordinary operations break invariants, or is such dangerous activity restricted to "experts only" functions?
For what it's worth: the Unicode standard *requires* conforming implementations to neither accept nor generate ill-formed Unicode sequences. Ref: Unicode Chapter3 C12 and C12a. John.
