It's probably worth specifically calling out that the "bytes" values refers to characters and NOT bytes, e.g. by adding an NB at the end: "NB: for multi-byte character sequences, this length is the number of characters and not the number of bytes." (Phrasing could be improved, but you should get the idea).
