I said that with the alternative of UnicodeScript as _normal class_ in 
my head, if saving the redundant internal hash map should matter.

Yes, for the semantics definition/explanation of Unicode script name, 
user should refer to the TR#24.

     if (script < UnicodeScript.LATIN)
to easily filter the special cases.
Same might be considered for SURROGATE, PRIVATE_USE, UNASSIGNED.
