group names have HTML in them
Created by: dcsan
sometimes group/room names come in like:
中国爱<img class="emoji emoji1f1e81f1f3" text="_web" src="/zh_CN/htmledition/v2/images/spacer.gif" />
I'm not sure how we should handle this - try and understand which emoji they are referring to and fix the group name to be ASCII?
at the least we should probably remove the spacer.gif
html slug?
