Call to `enhanced-resolve` converts `#` in paths to `\0#`, which crashes `eslint-plugin-import`

[ashmind]

Overview

When a path includes #, it seems that enhanced-resolve replaces it with \0# (https://github.com/webpack/enhanced-resolve#escaping). Unfortunately further up this causes a failure in eslint-plugin-import:

TypeError [ERR_INVALID_ARG_VALUE]: The argument 'path' must be a string or Uint8Array without null bytes. Received 'c:\\Development\\SharpLab\\source\\\x00#external\\mirrorsharp-codemirror-6-preview\\WebAssets\\node_modules\\@codemirror\\comma...

Why this library?

I could report this to enhanced-resolve, but their \0 escape seems to be well documented and by design. Happy to report there if you think that's the best option.

I could report this to eslint-plugin-import, however the problem depends on details resolver implementation, and eslint-plugin-import seems resolver-agnostic.

Proposed solution

Path returned by enhanced-resolve can be post-processed to replace \0# with #, which is the correct representation of the filesystem path.
