truncate shortens a string down to the number of characters passed as a parameter. If the number of characters specified is less than the length of the string, an ellipsis (…) is appended to the string and is included in the character count.

truncate takes an optional second parameter 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 parameter counts against the number of characters specified by the first parameter. For example, if you want to truncate a string to exactly 10 characters, and use a 3-character ellipsis, use 13 for the first parameter of truncate, since the ellipsis counts as 3 characters.
Ground control, and so on
You can truncate to the exact number of characters specified by the first parameter and show no trailing characters by passing a blank string as the second parameter:
