\Q\b doesn't work, because it returns \\b (you can verify it by print quotemeta '\b'). You can switch the order to make it work: \b\Q$kw\E\b .

There's another problem, though. \b matches word bounderies, but .NET is not considered a word: the dot is not a word character. Therefore, \b doesn't match at the beginning of '.NET'. Use look-around assertions with whitespace (if your words are delimited by whitespace).

($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord
