bookmark may contain extraneous characters

[interlocuteur]

Bookmarks displayed in the bookmarks panel may contain extraneous spaces or \n.
Problem is easy to demonstrate if you convert the following snippet of HTML:

<h2><a href="example.org/index.html">This is -
- a problematic example.</a></h2>"

Replace the 2 dashes with spaces (this editor delete extra spaces)
Convert this HTML file to PDF with weasyprint.
Display the bookmark list in your PDF viewer.

The bookmark contains extraneous spaces. It also contain an extraneous \n but your PDF viewer do not show it explicitely. However, you can see the \n using the API.
The problem happen when the anchor text is split on two lines in the HTML file.
