 To Display ``u'コンニチハ'`` right-adjusted on screen of 80 columns::
 
     >>> from wcwidth import wcswidth
     >>> text = u'コンニチハ'
     >>> print(u' ' * (80 - wcswidth(text)) + text)

+Use function ``wcwidth()`` to determine the length of a *single character*,
+and ``wcswidth()`` to determine the length of a *string of characters*.
+
+Function ``wcswidth()`` simply returns the sum of all values along a string,
+individually mapped over function ``wcwidth()``, or, ``-1`` in total
+if any part of the string's return value from ``wcwidth()`` results in
+a value of ``-1``.

+Return values of wcwidth are:
 
 ``-1``
   Indeterminate (not printable).

+Caveats
+=======
 
 This library does its best to return the most appropriate return value for a
 very particular terminal user interface where a monospaced fixed-cell
-rendering is expected.  As the POSIX Terminal programming interfaces do not
-provide any means to determine the unicode support level, we can only do our
-best to return the *correct* result for the given codepoint, and not what any
-terminal emulator particular does.
-
-Python's determination of non-zero combining_ characters may also be based on
-an older specification.
-
-You may determine an exacting list of these discrepancies using the project
-files `wcwidth-libc-comparator.py <https://github.com/jquast/wcwidth/tree/master/bin/wcwidth-libc-comparator.py>`_ and `wcwidth-combining-comparator.py <https://github.com/jquast/wcwidth/tree/master/bin/wcwidth-combining-comparator.py>`_.
