fails on regular expressions with Unicode property escapes

報告されたコマンド bunx jco componentize world.js --wit wit -o ts-typescript.wasm -d clocks -d random -d http で失敗を再現し、node_modules/.pnpm/change-case@5.4.4/node_modules/change-case/dist/index.js にある Unicode プロパティ正規表現を調査します。src/componentize.js の 305 行目付近と、報告された jco エントリポイントを通して失敗を追跡します。同じ入力を Wizer の初期化エラーなしで componentize できれば完了です。

I am trying to wrap typespec into a component. It pulls in change-case library which uses regular expressions with Unicode. componetize is failing on these regular expressions:

var SPLIT_LOWER_UPPER_RE = /([\p{Ll}\d])(\p{Lu})/gu;
var SPLIT_UPPER_UPPER_RE = /(\p{Lu})([\p{Lu}][\p{Ll}])/gu;
var SPLIT_SEPARATE_NUMBER_RE = /(\d)\p{Ll}|(\p{L})\d/u;
var DEFAULT_STRIP_REGEXP = /[^\p{L}\d]+/giu;

The code is from here:
node_modules/.pnpm/change-case@5.4.4/node_modules/change-case/dist/index.js
https://www.npmjs.com/package/change-case
https://github.com/blakeembrey/change-case/blob/main/packages/change-case/src/index.ts

$ bunx jco componentize world.js --wit wit -o ts-typescript.wasm -d clocks -d random -d http

Copilot says:

SpiderMonkey, the JavaScript and WebAssembly engine used in Mozilla Firefox, supports Unicode property escapes as part of the ECMAScript 2018 (ES9) specification. This feature allows you to use Unicode property escapes in regular expressions to match characters based on their Unicode properties.

Enabling Unicode Property Escapes in SpiderMonkey

To ensure that SpiderMonkey is compiled with support for Unicode property escapes, you need to use a version of SpiderMonkey that supports ECMAScript 2018 or later. Most modern versions of SpiderMonkey, including those used in recent versions of Firefox, already include this support.
