In the Chinese character input state, the default is full-width input mode; B>. In the English input state, the default is half-width input mode; C>. In full-width input mode, punctuation is 2 bytes; D>. In the half-angle input mode, the punctuation mark occupies 1 bytes; therefore: Characters in the Chinese character input state, accounting for 2 bytes (but do not exclude, they changed the default settings); The characters in the English input state, accounting for 1 bytes (but do not exclude, the default settings have changed);
