Parsing a char to u32
<p>As the questions states, how do I achieve this?</p>

<p>If I have a code like this:</p>

<pre><code>let a = "29";
for c in a.chars() {
    println!("{}", c as u32);
}
</code></pre>

<p>What I obtain is the unicode codepoints for 2 and 9:</p>

<ul>
<li>50</li>
<li>57</li>
</ul>

<p>What I want is to parse those characters into the actual numbers.</p>
