How to: output Euro symbol in pdfkit for nodejs

Question

Is it possible to display the Euro symbol in pdfkit for nodejs without having to embed an external font?

I am using pdfKit to generate invoices and would like to prefix my currency amounts with the Euro Symbol (€).

I've tried a number of approaches and none worked:

doc.font('Helvetica-Bold')
    .fontSize(12)
    .text('€', 10, 10); // Alt+0128 on keypad

doc.font('Helvetica-Bold')
    .fontSize(12)
    .text('\u20AC', 10, 10);

Could you include a bit more detail? Perhaps a small example that demonstrates the issue? – Jambeau

Turns out it is a font issue:

unicode works, but you have to make sure that the font you are using includes the characters you want to use. Unlike your operating system, PDFKit does not do any automatic font substitution.

I tested two fonts that were included with pdfkit. Both 'Helvetica-Bold' and 'Times-Roman' didn't work with the unicode symbols. I noticed in the documentation for fonts that you can add in your own fonts, so I gave the Cardo Font (hosted on Google Fonts) a go as it supports many unicode characters.

Sure enough, it worked. Here is the script I used for testing (Make sure you have the Cardo font available):

var PDFDocument = require('pdfkit');
var doc = new PDFDocument();

doc.registerFont('Cardo', 'Cardo/Cardo-Regular.ttf')

doc.font('Cardo')
    .fontSize(20)
    .text('Testing [\u20AC]', 10, 10);

doc.write('out.pdf');

If you're set on using Helvetica-Bold, download a copy of the font elsewhere (make sure it supports the unicode characters you're after) and register it as I have with the Cardo font.

So the answer is that it is not possible. – Blab

Here's a list of fonts that support the Euro sign. The website also has lists for other symbols. fileformat.info/info/unicode/char/20ac/fontsupport.htm – Spoonerism
