Detailed Description
UText struct.
Provides the interface between the generic UText access code and the UText provider code that works on specific kinds of text (UTF-8, noncontiguous UTF-16, whatever.)
Applications that are using predefined types of text providers to pass text data to ICU services will have no need to view the internals of the UText structs that they open.

(protected) pointer to a chunk of text in UTF-16 format.
May refer either to original storage of the source of the text, or if conversion was required, to a buffer owned by the UText.

(protected) Current iteration position within the text chunk (UTF-16 buffer).
This is the index to the character that will be returned by utext_next32().
- Stable:

(protected) Pointer to string or text-containin object or similar.
This is the source of the text that this UText is wrapping, in a format that is known to the text provider functions.

(private) Magic.
Used to help detect when UText functions are handed invalid or unitialized UText structs. utext_openXYZ() functions take an initialized, but not necessarily open, UText struct as an optional fill-in parameter. This magic field is used to check for that initialization. Text provider close functions must NOT clear the magic field because that would prevent reuse of the UText struct.

(protected) The highest chunk offset where native indexing and chunk (UTF-16) indexing correspond.
For UTF-16 sources, value will be equal to chunkLength.
