Substituting letters for numbers

Hello, Given a string: i994 where I want to replace the 'i' by a '1' the following regex succesfully replaces the letter by a number: s/(i)(\d\d\d)/1$2/; However, given a string: i99o where I want to replace the 'i' by a '1' and the 'o' by a '0' (zero), the following regex fails: s/(i)(\d

Matching Greek letters in UTF-8 file

Hi, I need to write a regex that matches any single Greek letter followed by a hyphen in a UTF-8 text file that is otherwise in English. How can I match the Greek alphabet (lower and upper case)? Thanks, Thomas -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands
