based on their displayed width, not their size in bytes.</p>
<p>This function creates a Wrapper on the fly with default settings.
If you need to set a language corpus for automatic hyphenation, or
need to wrap many strings, then it is suggested to create a Wrapper
and call its <a href="struct.Wrapper.html#method.wrap"><code>wrap</code> method</a>.</p>
<p>The result is a vector of strings. Use <a href="fn.wrap_iter.html"><code>wrap_iter</code></a> if you need an
iterator version.</p>
