A small quibble: I'd like to see a benchmark of a 'u' function implemented in C. Even if it was quite fast, I don't think such a function would bring the same benefits as restoring support for u'' literals. You claim that, but your argument doesn't actually support that claim (or I fail to see the argument). Python 2.6 code: this = u'that' Python 3.3 code: this = u('that') Not source compatible, not elegant. (Even though 2to3 could make this fix, it's still kinda ugly.)

No:

Python 2.6 code

this = u('that')

Python 3.3 code

this = u('that')

It is source compatible, and 100% so. As for elegance: I find the u prefix fairly inelegant already; the function removes just a little more elegance.
