Composed characters on a touchscreen

Hello world!
A lot of non-ASCII characters may be composed of a dead-key and a
subsequent ASCII character (for instance: ^ and a becomes â). Which
sequence of KeyEvents to a PtText widget must be follwed to succeed with
composed characters on a handmade touchscreen keyboard (in terms of
key_cap, .key_sym and .key_scan)?

The composing is done by the input driver, not by the widget. The widget
just needs to see an event with the appropriate value of key_sym (in the
case of the “â” character, the value is Pk_acircumflex or 0xE2).
