Variable cutZHStringConst

Type Declaration

• • (
        str: string | null | undefined,
        len: number,
        options?: { dotText?: string; hasDot?: boolean },
    ): string

  • 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
    Copy
