I agree with you that ICU is the best known library for
supporting Unicode.

Of course I know that text layout is out of scope of your library.
Just I want to stress the fact that the line breaking in some language
(Japanese in this case) is highly dependent upon text layout. For example,
some 'line breaking forbidden rule' is relaxed on newspaper-like text layout
situation as shown in "Requirements for Japanese Text Layout"[1].
