node_modules can behave as partly not excluded

[pp0rtal]

Describe the bug

Even if I put node_modules in the exclude (doc) config list, it can behave inconsistently:

• It can make the compiler fail
• It can result to silent high resources consumption (cf closed issues complex to reproduce)

As I need to install packages, I can't give an example on the playground.
However, I hosted a minimal example with every step to reproduce it in local.

Input code

./backend/node_modules/.bin/swc ./backend/ --out-dir ./backend_dist

Config

{
  "exclude": [
    "excluded_file",
    "node_modules"
  ]
}

Playground link

(See readme to reproduce in seconds on your machine)

Expected behavior

Successfully compiled: 1 file with swc (63.37ms)

Actual behavior

failed to load file

Caused by:
    stream did not contain valid UTF-8
failed to load file

Caused by:
    stream did not contain valid UTF-8
Successfully compiled: 1 file with swc (70.04ms)

Version

1.3.53

Additional context

I chose memoizerific package to make swc fail, but it can happen with other packages.
Also, I noted that node_modules don't behave as excluded and impact significantly performances.

Interesting note: If I remove node_module from the exclude list, I have way more errors. It demonstrates that swc ignores most of node_modules files, but not everything. The error is not my .swcrc exclude list config.

Similar issue in swc-cli project swc-project/cli#80
But maybe it's more core, not sure
