Description

Using the HTMLStripCharFilter may yield to an invalid HTML highlight.

The HTMLStripCharFilter has a special treatment of inline-elements (eg. "a", "b", ...). For theese elements the CharFilter ignores the tag and does not insert any split-character.

If you index
"""
<a>xxx</a>
"""
you get the word "xxx" starting at position 3 ending on position 10

If you highlight a search on "xxx", you will get
"""
<a><em>xxx</a></em>
"""
which is invalid HTML.
