Language::truncate() was soft-deprecated in 1.31 (2d2575852c01a180ccd75c8a4fa60d8db323eeb6 by @Petar.petkovic) and split into truncateForVisual (which counts characters) and truncateForDatabase (which counts bytes).
This task tracks the work to remove existing uses of Language::truncate() in production so that it can be hard-deprecated and then eventually removed.
