mchar_define_charset - Define a charset.
MSymbol mchar_define_charset (const char * name, MPlist * plist)
Define a charset. The mchar_define_charset() function defines a new charset and makes it accessible via a symbol whose name is name. plist specifies parameters of the charset as below:
The value specifies the method for decoding/encoding code-points in the charset. It must be Moffset, Mmap (default), Munify, Msubset, or Msuperset.
The value specifies the dimension of code-points of the charset. It must be 1 (default), 2, 3, or 4.
The value specifies the minimum range of a code-point, which means that the Nth byte of the value is the minimum Nth byte of code-points of the charset. The default value is 0.
The value specifies the maximum range of a code-point, which means that the Nth byte of the value is the maximum Nth byte of code-points of the charset. The default value is 0xFF, 0xFFFF, 0xFFFFFF, or 0xFFFFFFFF if the dimension is 1, 2, 3, or 4 respectively.
The value specifies the minimum code-point of the charset. The default value is the minimum range.
The value specifies the maximum code-point of the charset. The default value is the maximum range.
The value specifies whether the charset is ASCII compatible or not. If the value is Mnil (default), it is not ASCII compatible, else compatible.
The value specifies the final byte of the charset registered in The International Registry. It must be 0 (default) or 32..127. The value 0 means that the charset is not in the registry.
The value specifies the revision number of the charset registered in The International Registry. It must be 0..127. If the charset is not in The International Registry, the value is ignored. The value 0 means that the charset has no revision number.
The value specifies the minimum character code of the charset. The default value is 0.
If the method is Mmap or Munify, a data that contains mapping information is added to the m17n database by calling the function mdatabase_define() with the value as an argument extra_info, i.e. the value is used as a file name of the data.
Otherwise, this parameter is ignored.
If the method is Msubset, the value must is a plist of length 1, and the value of the plist must be a symbol representing a parent charset.
If the method is Msuperset, the value must be a plist of length less than 9, and the values of the plist must be symbols representing subset charsets.
Otherwise, this parameter is ignored.
If the dimension of the charset is 1, the value specifies whether or not to define a coding system of the same name whose type is Mcharset. A coding system is defined if the value is not Mnil.
Otherwise, this parameter is ignored.
