Function truncateByWeightedLength

Truncate a string by weighted UTF-16 length.

Code units from U+0000 through U+00FF count as one; all other code units count as two. Optional truncation text is appended after the length limit. This does not measure bytes or rendered width and can split surrogate pairs.

Usage:

import { truncateByWeightedLength } from "mazey";

const ret = truncateByWeightedLength("hello world", 5);
console.log(ret);
Copy

Output:

hello
