That's not quite what I was saying here. Note I said "wide variety of usage", not "widely used". Django is a web development framework—and its purpose is very clear and specific: to build a web app. Crucially, a web framework knows what its encoding constraints are at its boundaries, and it is supposed to enforce them. For examples, HTTP headers are known to be ASCII, HTML files have <meta ...> tags to declare encodings, etc. So if a user says (say) "what if I want to output non-ASCII in the headers?", your response is supposed to be "we don't let you do that because that's actually wrong". Contrast this with platform I/O where the library is supposed to work transparently without any knowledge of any encoding (or lack thereof) for the data it deals with, because that's a higher-level concern and you don't expect the library to impose artificial constraints of its own.
