Re: regex match unicode characters in ascii string

If I'm understanding you correctly, you want to remove anything that's not printable ASCII?

# Keep only printable ASCII plus CR, LF, TAB
$string =~ tr/\x09\x0A\x0D\x20-\x7E//cd;

# Keep only alphanumeric plus space
$string =~ tr/A-Za-z0-9 //cd;

Thank you!, I thought about this, but if I don't replace the extended ascii character with a space, how will i differentiate the group name with the role identifier? - 3dbc	[reply]

Hi 3dbc, replace the extended ascii character with a space `$string =~ tr/\x09\x0A\x0D\x20-\x7E/ /c;` [download] See the documentation of `tr/SEARCHLIST/REPLACEMENTLIST/cdsr` under "Quote-Like Operators" in perlop. Hope this helps, -- Hauke D	[reply] [d/l] [select]
