Disable line break between two .text() calls

[karimmakhloufi]

Question

I'm using pdfkit to generate text where syllables are differently colored.
I'm having an issue to avoid line breaks in the middle of a word because I call .text() each time I want to change color.
Is it possible to make that 2 calls are unbreakable ?

Code sample

You can test if you put this code in https://pdfkit.org/examples/browserify/browser.html

var doc = new PDFDocument();
var stream = doc.pipe(blobStream());

doc.fontSize(25)
  .text("aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa", {continued: true})
  .text("bb", {continued:true})
  .fillColor("red")
  .text("b", {continued: true}) 
doc.end();
stream.on('finish', function() {
  iframe.src = stream.toBlobURL('application/pdf');
});

As you can see, I need the multiple b to be one word but with different colors and it breaks

is there a way to avoid the break ?
