I just wanted to demonstrate multibyte chars including ASCII white spaces can be an identifier.
I understand now.

What do you exactly propose regarding white chars and multibyte chars here? Maybe you propose to consider non ASCII white spaces (treate them as ASCII white spaces)?
I propose the work with UTF white chars should be same like ASCII white chars. The current design is too simple - with possible pretty bad issues. Daniel's example is good - there is big gap in design.
