PHP Question

Removing emojis from variable

I'm using Smarty to pass in and display the contents of a

variable. Some users have Emoji characters (http://en.wikipedia.org/wiki/Emoji) in their
and I am wondering how I can either a) conditionally not display a user's
if it contains emojis or b) filter out emoji characters from
. Can this be done with Smarty? Can it be done with PHP in Smarty?

Answer Source

The emoji are encoded in the block U+1F300–U+1F5FF.

preg_replace('/\xEE[\x80-\xBF][\x80-\xBF]|\xEF[\x81-\x83][\x80-\xBF]/', '', $first_name)

this will strip those out
