<div class="textblock"><p>C API: Unicode stdio-like API. </p>
<h2>Unicode stdio-like C API</h2>
<p>This API provides an stdio-like API wrapper around ICU's other formatting and parsing APIs. It is meant to ease the transition of adding Unicode support to a preexisting applications using stdio. The following is a small list of noticable differences between stdio and ICU I/O's ustdio implementation.</p>
<ul>
<li>
Locale specific formatting and parsing is only done with file IO. </li>
<li>
u_fstropen can be used to simulate file IO with strings. This is similar to the iostream API, and it allows locale specific formatting and parsing to be used. </li>
<li>
This API provides uniform formatting and parsing behavior between platforms (unlike the standard stdio implementations found on various platforms). </li>
<li>
This API is better suited for text data handling than binary data handling when compared to the typical stdio implementation. </li>
<li>
You can specify a Transliterator while using the file IO. </li>
<li>
You can specify a file's codepage separately from the default system codepage. </li>
</ul>
