Please specify what version(s) of PowerPoint you are targeting: [ 365 ]

Expected / Desired Behavior / Question

On Bar chart type when using the dataLabelFormatCode with a value like #,##0.0"%" the generated pptx file is corrupted.

Observed Behavior

My demo numbers are

	value
A	15.5
B	20.32

The expected behavior is to show the numbers on the bar charts as 15.5% and 20.3%. The format code #,##0.0"%" is working fine if you set it in Powerpoint directly.

Steps to Reproduce

Create a bar chart with the following code

 let testdata = [{
    name: '',
    labels: ['A', 'B'],
    values: [15.5,20.32 ],
  }]
 slide.addChart(pptx.ChartType.bar, testdata, {
        catAxisLabelFontSize: 15,
        catAxisLabelColor: '75D4D6',
        catAxisLabelFontBold: true,
        catAxisLineShow: false,
        valAxisLineShow: false,
        valAxisHidden: true,
        lineSize: 4,
        barGapWidthPct: 50,
        dataLabelPosition: 'ctr',
        dataLabelFontSize: 10,
        dataLabelColor: '000000',
        dataLabelFormatCode: '#,##0.0"%"',
        showValue: true,
        showTitle : false,
        valGridLine: { style: 'none' },
        catGridLine: { style: 'none' },
        x: 1.81,
        y: 2.51,
        w: 1.94,
        h: 1.73,
      })

According to official Microsoft documentation, you can add symbols and characters by wrapping them with "".
another option is to use an escaping character. so in your case you should use: \%
escaping seems to be working on PptxGenJS, but "" seems to corrupt the file.

I'll try to fix this issue.
