Pdfkit: Strange character "Ð" every time I press "intro"

[cfibla]

Hello,
I'm trying to get a text from an object in NodeJs but I have a little problem:
For example:
doc.text(myObject.text);
if myObject.text is like (with "intro's"):
"THIS
IS
MY
TEXT"

when I render the PDF it looks like:
"THIS Ð
IS Ð
MY Ð
TEXT"

I've been looking for info, but I didn't found anything about this, am I the only person in the world??

There are probably strange invisible unicode characters in your text...

[cfibla]

Mmmm... but in console the text is clean, with no symbpls.

[alafr]

It can be some kind of space character and _look_ cleen.
Just to be sure, check it with charCodeAt()

for (i = 0; i < string.length; i++) {
  console.log(string.charCodeAt(i));
}

Which font are you using?

[cfibla]

Thanks for your answer alafr,
I'm using the default font of PDFkit. I tried your code with:
H(intro)E(intro)L(intro)L(intro)O
the result was:
72, 13, 10, 69, 13, 10, 76, 13, 10, 76, 13, 10, 79

Thanks, with these details the bug is easy to reproduce:
doc.text('H\r\nE\r\nL\r\nL\r\nO');
Apparently the character 13 (carriage return, \r) is not processed correctly by PDFKit, when using standard fonts.

As a workaround you can clean the line breaks with a regular expression:
string.replace(/\r\n|\r/g, '\n')

[cfibla]

It works pretty fine!
Thank you @alafr !

Although @alafr has found a workaround would it be possible to have a more permanent fix?

[unknowndomain]

Just for the record this issue is still reproducible and the fix above by @alafr to replace the \r\n carriage return with just \n new line.

although @alafr solution does seem to work on the output, if you have the pdf read by a reader (i.e. pdf.js) it will return a "UnkownErrorException" - " bad XRef entry"

Hi,
i think the XRef error comes from somewhere else. I load my data from a mysql database, change '\r\n' to '\n' and my PDF can be loaded without errors by any common reader (Adobe, PDF.js).
