It replaces every character in that character class (basically: the unusual ASCII control characters, plus anything outside ASCII) with: opening square bracket, followed by capital letter "U", followed by plus sign, followed by the numeric value of character being replaced, in uppercase hexadecimal, padded to a minimum of four digits, followed by closing square bracket It's a regular expression I use quite... regularly. It makes any non-ASCII characters stick out like a sore thumb, so you can see exactly what characters are in your string. `perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'`	[reply]
