Do you do any of the user education *about codec use* that you
recommend? The people I try to teach about coding invariably find it
difficult to understand. The problem is that the near-universal
intuition is that for "human-usable text" is pretty much anything *but
Unicode* will do. This is a really hard block to get them past.
There is very good reason why Unicode is plain text ("original" in
MAL's terms) and everything else is encoded ("derived"), but students
new to the concept often take a while to "get" it.
Maybe it's just me, but whether it's the teacher or the students, I am
*not* excited about the education route. Martin's simple rule *is*
simple, and the exceptions for using a "nonexistent" method mean I
don't have to reinforce---the students will be able to teach each
other. The exceptions also directly help reinforce the notion that
text == Unicode.
I grant the point that .decode('base64') is useful, but I also believe
that "education" is a lot more easily said than done in this case.
