What are the allowed character in snapchat username
<p><strong>I have been unable to find what the allowed characters are while creating a shapchat (<a href="https://www.snapchat.com/" rel="nofollow noreferrer">https://www.snapchat.com/</a>) username. Can anyone here share their knowledge regarding this?</strong></p>

<p>Context: I am creating a username validation system.</p>

<p>N.B. I have tried <a href="https://support.snapchat.com/en-US/ca/snaps" rel="nofollow noreferrer">support.snapchat.com</a> - but it provides no information regarding the allowed characters in a username.</p>
