Hey it’s very simple for national characters as well.
If you have problems with local chars just always put the string through chars.
In this case it is simply:

str.chars.upcase.to_s

Preseneted solution with regular expression doesn’t take into consideration string with national characters, i.e. not from regular a-z range.

How appropriate, the blog ate my whitespace! My example should look like: “Hello____________________world” becoming “Hello_world”.

Just to clarify David’s post, the error in your original function is that it modifies whitespace. It will replace all whitespace with a single space, including tabs or multiple spaces. Thus the string “Hello world!” will become “Hello World!” using your original function.

Thanks for the comment David.
Actually, the string will be modified, it will just out put a new string with upper case words.

However, I like your solution more, ill add it to the post!

This will actually modify the string, so if you had (substituting _ for spaces) “hello___how___are___you” would be replaced with “Hello_How_Are_You”, i.e. the spaces are removed.

This might be a better solution:

str.gsub(/^[a-z]|\s+[a-z]/) { |a| a.upcase }
