First row's header quoted

• Operating System: Docker node:8-slim
• Node Version: 8.16
• NPM Version: 6.4.1
• csv-parser Version: 2.3.0

Expected Behavior

Data of

col1,col2,col3
a,2,foobar

becomes:

[
	Row {
		col1: 'a',
		col2: '2',
		col3: 'foobar'
	}
]

Actual Behavior

[
	Row {
		'col1': 'a',
		col2: '2',
		col3: 'foobar'
	}
]

Notice how the first column’s header has a single quote around it: 'col1'.

How Do We Reproduce?

File was created from Excel (using 16.24 via Office 365 subs). File has been checked with text editor and confirmed does not have a quote around the first column’s header.

test-csv-parser.csv.zip

Code

const csv = require('csv-parser')
const fs = require('fs')
const results = [];

fs.createReadStream('test-csv-parser.csv')
  .pipe(csv())
  .on('data', (data) => results.push(data))
  .on('end', () => {
    console.log(results);
  });

@daytonmills I discovered that this issue can be reproduced by simply setting the encoding to UTF-8-BOM within notepad++. This is also the format that excel uses when saving csv files by default. A workaround is to manually change the encoding to UTF-8.

For future people stumbling on my comment. https://github.com/mafintosh/csv-parser#byte-order-marks documents the issue well and contains a solution.
