Hi all,<div><br></div><div>I am not really familiar with regexp, an I am facing a problem. I have some strings containing unicode sequences (like &quot;\u****&quot;), and I would like to replace them with html sequences (such that &quot;\u****&quot; becomes &quot;&amp;#x****;&quot;). I think I can do that with boost regexp, but I really do not know how. The major problem is that I do not now in advance what are the characters for &quot;****&quot;. I however know that they are always 4 and alphanumeric. So, I have to detect them and also append after a &quot;;&quot;.</div>

<div>Do you have any hint on how to do that?</div><div><br></div><div>Best regards,</div><div><br></div><div>Olivier</div>
