+Conversion in Symbian C++ and GNU C</title><shortdesc>Symbian C++ supports character conversion between Unicode and other
+native character sets.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>GNU C supports character conversion: <ul>
+<li><p>between Unicode and other native character sets</p></li>
+<li><p>from a native character set to another native character set.</p></li>
+</ul></p>
+<p>The following example illustrates the steps to be followed to convert from
+one native character set to another native character set. In GNU C it is straightforward.
+In Symbian C++ more lines of code are needed to do the same work. The example
+converts a string from the ISO-8859-1 character set to the ISO-8859-2
+character set. </p>
