Hi all. I am processing some twitter user names that have unwanted multibyte UTF-8 characters in them. I got the ORD values of these using the following script: 
use feature ':5.10';
my $foo = '⁦JenAFifield⁩';
foreach my $i (0..length($foo)) {
    $char = substr($foo,$i,1);
    $charnum = ord($char);
    say "$char\t$charnum"; 
}

but I see this forum is replacing the characters with some other encoding I don't recognize. In my editor (Komodo) They are at the beginning and end of the $foo string. The beginning one is a dotted box with LRI inside, and the end one has the same box with PDI inside. The script returns: 
    226
    129
    166
J    74
e    101
n    110
A    65
F    70
i    105
f    102
i    105
e    101
l    108
d    100
    226
    129
    169

where in my editor the undisplayable char is a black rectangle with HOP inside. I'm not sure why it displays like that because ASCII 129 should be u-umlaut.

Am wondering how to do a regexp that will get rid of these chars. Based on numbers shown here I tried $foo =~ s/\x8294|\x8297//g; but that didn't do it. Can anyone help?
