how to add a new font or style?

I'm having problems with fonts in the pdffont.js file.
The font I need to add is times new roman. I couldn't add it and in the main sources I didn't find any serif
`
let _stdFonts = ["arial", "helvetica", "sans-serif ", "courier ", "monospace ", "ocr "];

let _kFontFaces = [
    "quicktype,arial,helvetica,sans-serif",							// 00 - QuickType - sans-serif variable font
    "quicktype condensed,arial narrow,arial,helvetica,sans-serif",	// 01 - QuickType Condensed - thin sans-serif variable font
    "quicktypepi,quicktypeiipi",										// 02 - QuickType Pi
    "quicktype mono,courier new,courier,monospace",					// 03 - QuickType Mono - san-serif fixed font
    "ocr-a,courier new,courier,monospace",							// 04 - OCR-A - OCR readable san-serif fixed font
    "ocr b mt,courier new,courier,monospace"							// 05 - OCR-B MT - OCR readable san-serif fixed font
];

let _kFontStyles = [
    // Face		Size	Bold	Italic		StyleID(Comment)
    // -----	----	----	-----		-----------------

`Is this where I add? Like?

Start by reading pdffont.js around _stdFonts, _kFontFaces, and _kFontStyles to understand how the existing font faces and styles are represented. The issue names no tests, entry point beyond these arrays, or acceptance condition, so confirm the supported approach and expected result with maintainers before making a change.
