-// The job of __unwrap_iter is to lower contiguous iterators (such as

+// The job of __unwrap_iter is to remove iterator wrappers (like reverse_iterator or __wrap_iter),
+// to reduce the number of template instantiations and to enable pointer-based optimizations e.g. in std::copy.
 // In debug mode, we don't do this.

-// __unwrap_iter is non-constexpr for user-defined iterators whose

 // Some algorithms (e.g. std::copy, but not std::sort) need to convert an

-// are random-access, we can do this portably using iterator arithmetic; this

- * Unicode column width estimates.
- *
- * Unicode can be stored in several formats: UTF-8, UTF-16, and UTF-32.
- * Depending on format the relation between the number of code units stored and
- * the number of output columns differs. The first relation is the number of
- * code units forming a code point. (The text assumes the code units are
- * unsigned.)
- * - UTF-8 The number of code units is between one and four. The first 127
- *   Unicode code points match the ASCII character set. When the highest bit is
- *   set it means the code point has more than one code unit.
- * - UTF-16: The number of code units is between 1 and 2. When the first
- *   code unit is in the range [0xd800,0xdfff) it means the code point uses two
- *   code units.
- * - UTF-32: The number of code units is always one.
- *
- * The code point to the number of columns isn't well defined. The code uses the
- * estimations defined in [format.string.std]/11. This list might change in the
- * future.
- *
- * The algorithm of @ref __get_string_alignment uses two different scanners:
- * - The simple scanner @ref __estimate_column_width_fast. This scanner assumes
- *   1 code unit is 1 column. This scanner stops when it can't be sure the
- *   assumption is valid:
- *   - UTF-8 when the code point is encoded in more than 1 code unit.
- *   - UTF-16 and UTF-32 when the first multi-column code point is encountered.
- *     (The code unit's value is lower than 0xd800 so the 2 code unit encoding
- *     is irrelevant for this scanner.)
- *   Due to these assumptions the scanner is faster than the full scanner. It
- *   can process all text only containing ASCII. For UTF-16/32 it can process
- *   most (all?) European languages. (Note the set it can process might be
- *   reduced in the future, due to updates in the scanning rules.)
- * - The full scanner @ref __estimate_column_width. This scanner, if needed,
- *   converts multiple code units into one code point then converts the code
- *   point to a column width.
- *
- * See also:
- * - [format.string.general]/11

+//   Unicode code points match the ASCII character set. When the highest bit is
+//   set it means the code point has more than one code unit.
+// - UTF-16: The number of code units is between 1 and 2. When the first

+//   code units.

+
+History
+-------
+
+olefile is based on the OleFileIO module from
+`PIL <http://www.pythonware.com/products/pil/index.htm>`_, the excellent
+Python Imaging Library, created and maintained by Fredrik Lundh. The
+olefile API is still compatible with PIL, but since 2005 I have improved
+the internal implementation significantly, with new features, bugfixes
+and a more robust design. From 2005 to 2014 the project was called
+OleFileIO\_PL, and in 2014 I changed its name to olefile to celebrate
+its 9 years and its new write features.
+
+As far as I know, olefile is the most complete and robust Python
+implementation to read MS OLE2 files, portable on several operating
+systems. (please tell me if you know other similar Python modules)
+
+Since 2014 olefile/OleFileIO\_PL has been integrated into
+`Pillow <http://python-imaging.github.io/>`_, the friendly fork of PIL.
+olefile will continue to be improved as a separate project, and new
+versions will be merged into Pillow regularly.
+
+Main improvements over the original version of OleFileIO in PIL:
+----------------------------------------------------------------
+
+-  Compatible with Python 3.x and 2.6+
+-  Many bug fixes
+-  Support for files larger than 6.8MB
+-  Support for 64 bits platforms and big-endian CPUs
+-  Robust: many checks to detect malformed files
+-  Runtime option to choose if malformed files should be parsed or raise
+   exceptions
+-  Improved API
+-  Metadata extraction, stream/storage timestamps (e.g. for document
+   forensics)
+-  Can open file-like objects
+-  Added setup.py and install.bat to ease installation
+-  More convenient slash-based syntax for stream paths
+-  Write features
+
+Documentation
+-------------
+
+Please see the `online
+documentation <https://bitbucket.org/decalage/olefileio_pl/wiki>`_ for
+more information, especially the `OLE
+overview <https://bitbucket.org/decalage/olefileio_pl/wiki/OLE_Overview>`_
+and the `API
+page <https://bitbucket.org/decalage/olefileio_pl/wiki/API>`_ which
+describe how to use olefile in Python applications. A copy of the same
+documentation is also provided in the doc subfolder of the olefile
+package.
+
+Real-life examples

+A real-life example: `using OleFileIO\_PL for malware analysis and

+Updating Unicode Version
+------------------------
 
 Regenerate python code tables from latest Unicode Specification data files::
 
    tox -e update
 
+The script is located at ``bin/update-tables.py``, requires Python 3.9 or

+Building Documentation
+----------------------
+

+# Fields:
+#   code_point(s): one or more code points in hex format, separated by spaces
+#   type_field :RGI_Emoji_ZWJ_Sequence
+#     The type_field is a convenience for parsing the emoji sequence files, and is not intended to be maintained as a property.
+#   short name: CLDR short name of sequence; characters may be escaped with \x{hex}.
+#
+# For the purpose of regular expressions, the above type field defines the name of
+# a binary property of strings. The short name of the property is the same as the long name.
+#
+# Characters and sequences are listed in code point order. Users should be shown a more natural order.
+# See the CLDR collation order for Emoji.
