Maybe tr will work for you:

irb(main):012:0> "abcdefghijk".tr "abc", "123"
=> "123defghijk"

It supports character ranges, and padding the second argument
with its last character if it's shorter than the first one:

"hello".tr('aeiou', '*')    #=> "h*ll*"
"hello".tr('^aeiou', '*')   #=> "*e**o"
"hello".tr('el', 'ip')      #=> "hippo"
"hello".tr('a-y', 'b-z')    #=> "ifmmp"

I was having some problems testing your cases, I think because of the
strange chars, maybe that's the source of your problems too?

Hope this helps,

Jesus.
