[issue2799] Remove PyUnicode_AsString(), rework PyUnicode_AsStringAndSize(), add PyUnicode_AsChar()

[Stefan Behnel]

Stefan Behnel <scoder at users.sourceforge.net> added the comment:

While PyUnicode_AsStringAndSize() may be a better solution if the length
is required, PyUnicode_AsString is enough() when it is not required. So
I don't buy that argument. Since there are dedicated UTF-8 encoding
functions, both functions are pure convenience anyway.

Embedded \0 bytes can bite you, but that's completely unrelated to the
issue discussed here.

I wouldn't oppose renaming the function, but I don't see why it should go.
