initial_invocation

int MCodingInfoISO2022::initial_invocation[2]

designations

char MCodingInfoISO2022::designations[32]

Table of code extension elements. The Nth element corresponds to the Nth charset in charset_names, which is an argument given to the mconv_define_coding() function.

If an element value is 0..3, it specifies a graphic register number to designate the corresponds charset. In addition, the charset is initially designated to that graphic register.

If the value is -4..-1, it specifies a graphic register number 0..3 respectively to designate the corresponds charset. Initially, the charset is not designated to any graphic register.
