Unicode Escape

Convert a string to Unicode escaped values. Rust

let sb = chilkat::StringBuilder::new();

let str = "bôn".to_string();
let charset = "not_used".to_string();

// Unicode escape all chars using \uHHHH
let _ = sb.set_string(&str).is_ok();
let _ = sb.encode("unicode-escape-all", &charset);
println!("{}", sb.get_as_string().unwrap_or_default());
// Output is \u0062\u00f4\u006e

// Unicode escape only 8bit chars using \uHHHH
let _ = sb.set_string(&str).is_ok();
let _ = sb.encode("unicode-escape-8bit", &charset);
println!("{}", sb.get_as_string().unwrap_or_default());
// Output is b\u00f4n

// To use uppercase hex chars (A-F), add "-upper" to the encoding name
let _ = sb.set_string(&str).is_ok();
let _ = sb.encode("unicode-escape-all-upper", &charset);
println!("{}", sb.get_as_string().unwrap_or_default());
// Output is \u0062\u00F4\u006E

// Unicode escape all chars using \u{HHHH}
let _ = sb.set_string(&str).is_ok();
let _ = sb.encode("unicode-escape-all-curly-upper", &charset);
println!("{}", sb.get_as_string().unwrap_or_default());
// Output is \u{0062}\u{00F4}\u{006E}

// Unicode escape 8bit chars using HTML hex &#xH;
let _ = sb.set_string(&str).is_ok();
let _ = sb.encode("unicode-escape-8bit-html-hex", &charset);
println!("{}", sb.get_as_string().unwrap_or_default());
// Output is bôn

// Unicode escape all chars using HTML decimal &#D;
let _ = sb.set_string(&str).is_ok();
let _ = sb.encode("unicode-escape-all-html-dec", &charset);
println!("{}", sb.get_as_string().unwrap_or_default());
// Output is bôn

// Unicode escape all chars using u+HHHH
let _ = sb.set_string(&str).is_ok();
let _ = sb.encode("unicode-escape-all-plus", &charset);
println!("{}", sb.get_as_string().unwrap_or_default());
// Output is u+0062u+00f4u+006e

// Unicode escape 8bit chars using angled brackets <HHHH>
let _ = sb.set_string(&str).is_ok();
let _ = sb.encode("unicode-escape-8bit-angle-upper", &charset);
println!("{}", sb.get_as_string().unwrap_or_default());
// Output is b<00F4>n
