Here a Sample Code:

Code

alias test {

  var %spec.asctmp 🤣
  var %spec.asc $asc(🤣)
  var %spec.asc1 $asc(%spec.asctmp)

  var %spec.chrtmp $chr(55358)
  var %spec.chr $chr(%spec.asc)
  var %spec.chr1 $chr(%spec.asc1)

  echo -a SPEC.ASCTMP: %spec.asctmp
  echo -a SPEC.ASC: %spec.asc
  echo -a SPEC.ASC1: %spec.asc1
  echo -a SPEC.CHRTMP: %spec.chrtmp
  echo -a SPEC.CHR: %spec.chr
  echo -a SPEC.CHR1: %spec.chr1
  echo -a Copy & Paste Character: 🤣
  echo 4 -a Can anyone explain this ?

}

Why is the smiley face displayed in the Mirc when copied and pasted, but not with $chr
