Special type of string replacement

Hi,

I want to insert the "​" character in between each character of
a string contained in @user.email. So if the string output were
"me@mine.com", the result would be
"m​e​@​m​i​n​e​.​c​o​m".

Thanks for the info, - Dave

Something like this will do:
email = "me@mine.com"
email[0..-1].gsub(/./){|c| c+"​"}+email[-1..-1]

p "astring".split("").join("​")

I guess you want that to be email[0..-2] not email[0..-1] (otherwise you'll
have the last character twice). Anyway, here's my gsub solution:
email.gsub(/(.)(?=.)/, '\1​')

HTH,
