Crate unicode_width_utils 

A thin-wrapper for the unicode-width crate with additional functionalities.

This crate provides UnicodeWidth which can dynamically measure character and string widths based on whether they should be treated as CJK (East Asian Ambiguous) widths.

It also provides a helper method to truncate strings to a maximum display width.

Examples

use unicode_width_utils::UnicodeWidth;

// Create an instance with the default CJK setting.
let uw = UnicodeWidth::new();
assert_eq!(uw.char('A'), 1);

// Explicitly specify CJK behavior.
let non_cjk = UnicodeWidth::with_cjk(false);
let cjk = UnicodeWidth::with_cjk(true);

// Ambiguous CJK characters (like '█') have width 1 or 2.
assert_eq!(non_cjk.char('█'), 1);
assert_eq!(cjk.char('█'), 2);

// Truncate a string to a maximum width of columns.
let truncated = cjk.truncate("A█B", 2);
assert_eq!(truncated, "A");
