missing whitespace for file with BOM(UTF-8)

Bug Report

• 4.5.1:
• 2.2.2:
• Node.js API

TypeScript code being linted

[BOM]import * as $t from 't';

with tslint.json configuration:

"whitespace": [
      true,
      "check-branch",
      "check-decl",
      "check-operator",
      "check-module",
      "check-separator",
      "check-type",
      "check-typecast"
    ]

Actual behavior

.ts[1, 2]: missing whitespace

Expected behavior

No error

I have a similar issue with UTF-8 + BOM encoded files and tslint.json configuration:

"align": [
    true,
    "statements"
]

Actual behaviour

.ts[2, 1]: statements are not aligned
.ts[3, 1]: statements are not aligned
etc.

(reported for every statement in the file that is at the beginning of a line)

Expected behavior

No error

We have same whitespace issues with files having utf-8 with BOM encoding.
Its the check-module argument which causes this.

We have the same problem with the whitespace rule, it's the "check-typecast" option that is the cause.
I think the problem is for everyone using Visual Studio (and maybe others).

We use tslint: 5.3.2 and TypeScript 2.3.3.

We are also having a similar issue with files that were edited in Visual Studio. The files are in UTF8-BOM format. With tslint 5.2.0 they lint without issue but with 5.3.2 we get a "missing whitespace" error on line [1,2] for every file. If we edit the file to remove the BOM then tslint is happy again. I seem to remember something like this happening before so this might be some sort or regression.

Is there any update on this issue? As of 5.5.0 it still appears to be a problem. Or if someone knows of a way to get Visual Studio 2017 to save without the BOM that would work too.
