Detailed Description
       Support for m17n library users to debug their programs.

       The m17n library provides the following facilities to support the library users to debug their programs.

       o Environment variables to control printing of various information to stderr.
	 o MDEBUG_INIT -- If set to 1, print information about the library initialization on the call of M17N_INIT().
	 o MDEBUG_FINI -- If set to 1, print counts of objects that are not yet freed on the call of M17N_FINI().
	 o MDEBUG_CHARSET -- If set to 1, print information about charsets being loaded from the m17n database.
	 o MDEBUG_CODING -- If set to 1, print information about coding systems being loaded from the m17n database.
	 o MDEBUG_DATABASE -- If set to 1, print information about data being loaded from the m17n database.
	 o MDEBUG_FONT -- If set to 1, print information about fonts being selected and opened.
	 o MDEBUG_FLT -- If set to 1, 2, or 3, print information about which command of Font Layout Table are being executed. The bigger number
	   prints the more detailed information.
	 o MDEBUG_INPUT -- If set to 1, print information about how an input method is running.
	 o MDEBUG_ALL -- Setting this variable to 1 is equivalent to setting all the above variables to 1.
	 o MDEBUG_OUTPUT_FILE -- If set to a file name, the above debugging information is appended to the file. If set to 'stdout', the
	   information is printed to stdout.
       o Functions to print various objects in a human readable way. See the documentation of mdebug_dump_XXXX() functions.
       o The hook function called on an error. See the documentation of mdebug_hook().

Detailed Description
       Chartable objects and API for them.

       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.

Typedef Documentation
   typedef struct MCharTable MCharTable
       Type of chartables. The type MCharTable is for a chartable objects. Its internal structure is concealed from application programs.

Variable Documentation
   MSymbol Mchar_table
       Symbol whose name is 'char-table'. The symbol Mchar_table has the name 'char-table'.
