Thank you, Martin and Stephen, for the suggestions and comments.
For your information:
We decided that all NumPy arrays of unicode strings will use UCS4 for
internal representation. When an element of the array is selected, a
unicodescalar (which inherits directly from the unicode builtin type but
has attributes and methods of arrays) will be returned. On wide
builds, the scalar is a perfect match. On narrow builds, surrogate
pairs will be used if they are necessary as the data is copied over to
the scalar.
Best regards,
-Travis
