从Ruby的字符串末尾删除注册商标

Question

I am trying to remove a registered trademark from the end of a string so I can compare the two string's Levenshtein normalized distance and get an accurate number.

Does anyone know an easy way to strip the registered trademark symbol off the end of a string in Ruby?

For example:

example_name1 = Tylenol®
example_name2 = Tylenoloafjd

Answer 1

If you can do such things:

1. Make sure you're using ruby 2.0 or later.
2. Make sure your editor is encoding the actual file in UTF-8

And then you can do it just like normal:

example_name1.chomp!("®")
