Steps to reproduce

Output the character sequence twice using a tool of your choice: Esc % G E2 A3 BF Esc % @

Expected Behavior

Each time, the unicode character 28FF ⣿ (Braille Pattern Dots-12345678) will be printed.

Actual Behavior

The correct character is printed the first time, the second time (and any subsequent times) prints "⣿".

From my reading of the code, this is because Esc % @ (Select Default Character Set) correctly disengages UTF-8 by calling DesignateCodingSystem in ActionCsiDispatch. However, its companion seuqnece Esc % G (Select UTF-8 Character Set) is not handled and thus the sequence is never again rendered in Unicode.
