<p>This tests for a bug where quotes escaped by PHP when using <code>preg_replace</code> with the <code>/e</code> modifier must be correctly unescaped (hence the <code>_UnslashQuotes</code> function found only in PHP Markdown).</p> <p>Headers below should appear exactly as they are typed (no backslash added or removed).</p> <h1>Header "quoted\" again \""</h1> <h2>Header "quoted\" again \""</h2> <h3>Header "quoted\" again \""</h3> <p>Test with tabs for <code>_Detab</code>:</p> <pre><code>Code 'block' with some "tabs" and "quotes" </code></pre>
