SWC produces invalid output without mininification

[AlfonzAlfonz]

Describe the bug

SWC correctly transpiles unicode code point escapes when minification is true, but leaves them as is without it. This results in invalid ES5 syntax.

Input code

const x = "\u{20BB7}";

Config

{
  "jsc": {
    "parser": {
      "syntax": "ecmascript"
    },
    "target": "es5"
  },
  "minify": false
}
