Detailed Description

       Chartable objects and API for them.

       Symbol whose name is 'char-table'.

       The m17n library supports enormous number of characters. Thus, if attributes of each character are to be
       stored in a simple array, such an array would be impractically big. The attributes usually used, however,
       are often assigned only to a range of characters. Even when all characters have attributes, characters of
       consecutive character code tend to have the same attribute values.

       The m17n library utilizes this tendency to store characters and their attribute values efficiently in an
       object called Chartable. Although a chartable object is not a simple array, application programs can
       handle a chartable as if it is an array. Attribute values of a character can be obtained by accessing a
       Chartable for the attribute with the character code of the specified character.

       A chartable is a managed object.

       The symbol Mchar_table has the name 'char-table'.
