           Summary: HTML Named Character References in Markdown Are Not

Test file for reproducing bug.

SUMMARY
When certain HTML named character references appear in a Markdown file, then
those named character references are not parsed correctly. I only tested the
named character references "“" and
"”", but I'm sure the problem is not isolated to them.

STEPS TO REPRODUCE
1. Open the attached file test.html in a web browser.
2. Open the attached file test.md in Okular.
3. Compare the displays of the two files.

OBSERVED RESULT
Okular displays the named character references "“" and
"”" verbatim. However, Okular does correctly parse the
ostensibly equivalent "“" and "”".

EXPECTED RESULT
Okular should parse the Markdown "“" as the unicode
character U+201C ("Left Double Quotation Mark") and "”"
as the unicode character U+201D ("Right Double Quotation Mark").
