detecting special characters ⚠️

[NewzNZ]

Hi there
Am using a script to pull headlines from an RSS feed & just wondering if there's a way to detect special characters in a string to set up an ignore?
One of the offending characters is:

Have tried:
if {[string match ** $var]} {

and:
if {[string match *\* $var]} {

...but no luck. Am guessing perhaps the script language dosn't recognise these items?
Thanks in advance for any help/ideas...

This is a known trouble with TCL and emoji.
You can have a look to https://forum.eggdrop.fr/Hack-anti-emoj ... -1974.html (sorry, in french) on the way to ride them off.
