When there's no whitespace after </sup>, we get a RuntimeException. Seems to be from liblouis (CC @bertfrees @egli).

To reproduce:

  1. Input document:
<?xml version="1.0" encoding="UTF-8"?>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:epub="http://www.idpf.org/2007/ops" xml:lang="no" lang="no">
    <head>
        <meta charset="utf-8"/>
        <title>TEST</title>
        <meta name="dc:identifier" content="TEST"/>
    </head>
    <body>
        <section epub:type="bodymatter chapter" id="section1">
            <h1 id="h1">TEST</h1>
            <p><sup>rs</sup>4954</p>
        </section>
    </body>
</html>

  1. Run through "HTML to PEF (NLB)"

  2. Exception

  1. Insert a space after </sup> and try again, and it will succeed.

Looks like a Liblouis bug indeed.

I've created an issue: liblouis/liblouis#886.

By the way what is the correct translation of this example? I suspect that "⠨⠦⠗⠎⠼⠬⠙⠊⠑⠙" is wrong, it would be more logical if the "⠼" came after the "⠬". @josteinaj @KariRudjord Can you please check?

Yes, I think you're right. The "⠼" should come after the "⠬".

<sup>: ⠨⠦
rs: ⠗⠎
</sup>: ⠬
number: ⠼
4954: ⠙⠊⠑⠙

⇓

⠨⠦⠗⠎⠬⠼⠙⠊⠑⠙

(@KariRudjord: correct me if I'm wrong)

Could the ordering of the number sign vs end of </sup> be the same as the ordering of </strong></em> vs </strong></em>? (can't find the github issue for it)
