UTF8 files with BOM produce E999 "unexpected token"
I tried using ruff 0.0.191 (Python 3.9 on Windows 10) to check a file that is encoded in UTF8 with BOM (byte order mark). I used the default options for ruff.
Ruff reported a E999 SyntaxError: Got unexpected token in line 1 column 2 (and then apparently stopped processing further rules except for line length warnings).
When I changed the encoding of the file to UTF8 without BOM, ruff worked as expected and no E999 was reported.
As a workaround I can just change the encoding of the files to make sure no BOM is present, but I think it would be nice if ruff would be able to handle any of the usual source encodings.
