Hyphens aren't special outside of a character class. What makes you think they are at fault?

If your 'words' might contain punctuation, you can escape meta characters using quotemeta or synonymously \Q .. \E

Imagine these values: banana => 25 bana => 20 bana-na => 15 na => 10 For the translation to, let's say: bana-na,banana Currently the output is: 20-10,25 That's what made me thought the hyphens were a special case...	[reply]

No, but they are being marked as word boundaries, and so they pass the regex I gave before. For the situation you've described, the only obvious solution I can see is to traverse the key list from long to short as I've shown in Re^5: using hashes. Things get messy with replacement lists when your keys are not independent. #11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.	[reply]
