A flag to control printing of charset text property on printing a string.
The value should be nil, t, or default.
If the value is nil, don't print the text property charset.
If the value is t, always print the text property charset.
If the value is default, print the text property charset only when
the value is different from what is guessed in the current charset
priorities. Values other than nil or t are also treated as
default.
Probably introduced at or before Emacs version 23.1.
