For non-embedded fonts, map softhyphen (0x00AD) to regular hyphen (0x002D) (issue 9084)

Browse Source 
In the PDF file, the `ToUnicode` data first maps the hyphen correctly, and then *overwrites* it to point to the softhyphen instead. That one cannot be rendered in browsers, and an empty space thus appear instead.

Fixes 9084.
