Those are control characters of some type. That particular one is "Delete" - character \x7F. Assuming they are all the same, you can match against that. It might be better to match against a character class though, in case they vary. Try: `$text =~ /\p{Control}/;` to match, or `$text =~ s/\p{Control}//g;` to remove.	[reply] [d/l] [select]

The trick is to determine the ascii value of the character. Once you have that you can take its octal value and use ie \035 to match for it, where /s/035/the octal value of that character/. An entirely different approach, although far less likely to work is to simply use . which will match 1 character, regardless of what it is. Ofcourse this depends very heavily on whether the text you're trying to match has a specific order or not. Remember rule one...	[reply]
