"truncate" takes an optional second argument that specifies the sequence of characters to be appended to the truncated string. By default, this is an ellipsis (…), but you can specify a different sequence.
The length of the second argument counts against the number of characters specified by the first argument. For example, if you want to truncate a string to exactly 10 characters, and use a 3-character ellipsis, use 13 for the first argument of
truncate, since the ellipsis counts as 3 characters.
Ground control, and so on
