To Reproduce

npm install
npm run build

Current vs. Expected behavior

When I build the project for reproduction with Node v20.11.0, I get:

> Build error occurred
Error: Failed to collect page data for /

When I build the project with Node v20.12.2, I don't get any errors, but browsers throw Uncaught SyntaxError: Invalid or unexpected token when I access the app.

next build (local)

Additional context

It seems that minification removes quotes unexpectedly. swcMinify: false makes the build work properly.

This problem happens when an object has a key with "・" (U+30FB KATAKANA MIDDLEDOT), like { 'a・': '' } . Similar issue here: https://github.com/evanw/esbuild/issues/1599
