Unable to parse utf-8 BOM if sub dependency jsonc-parser is upgraded

[lukeapage]

I use renovate to upgrade the lock file and it updated

jsonc-parser@^3.0.0

from 3.0.0 to 3.2.0

  1:2  error  Expected a JSON object, array or literal  json/*

It looks like it was caused by this:

microsoft/node-jsonc-parser@009d0a6

I guess that eslint-plugin-json should remove a utf8 bom prior to passing it in?

Since the spec says that the BOM shouldn't be added, I think its fair for a linting tool to complain about it.

Implementations MUST NOT add a byte order mark to the beginning of a
JSON text. In the interests of interoperability, implementations
that parse JSON texts MAY ignore the presence of a byte order mark
rather than treating it as an error.

While the spec allows for parsers to ignore it, I don't think linters should.
