I presume that most 2.6 code has problems other than u'' when attempting to run under 3.x. Why?

Since writing the above, I realized that the following is a realistic scenario. 2.6 or 2.7 code a) uses has/set/getattr, so unicode literals would require a change; b) uses non-ascii chars in unicode literals; c) uses (or could be converted to use) print as a function; and d) otherwise uses a common 2-3 subset. Such would only need the u prefix addition to run under both Pythons. This works the other way, of course, for backporting code. So I am replacing 'most' with 'some unknown-to-me fraction' ;-).
