Invisible/unprintable character appended to result

[paddotk]

Marked version:
3.0.8

Describe the bug
Note: Not tried with 4.0.0 since I'm running into another blocking issue there, but since I can't find any issues or changelogs addressing this bug, I assume the issue hasn't been resolved yet.

When parsing a string with marked(), the returned string has an invisible character at the end. This makes some of my unit tests fail unless I .trim() it first.

To Reproduce
Steps to reproduce the behavior:
Use marked() on any string.
You can see there is an invisible character by checking the length of the output string:

const str = 'Hello there';
console.log(utils.parseMarkdown(str).length); // 19
console.log(utils.parseMarkdown(str).trim().length); // 18
console.log(utils.parseMarkdown(str)[18]); //

yes marked renderers add a newline character (\n) at the end of the markdown. That is by design.
