In this task, the goal is to find the <em>character</em> length of a string. This means encodings like [[UTF-8]] need to be handled properly, as there is not necessarily a one-to-one relationship between bytes and characters.

Since Java 1.5, the actual number of characters can be determined by calling the codePointCount method.
String str = "\uD834\uDD2A"; //U
int length1 = str.length(); //2
int length2 = str.codePointCount(0, str.length()); //1
Line 209 ⟶ 208:
var len1 = str1.length; //13
var str2 = "\uD834\uDD2A"; //U
var len2 = str2.length; //2
