Bug Description

STEPS TO REPRODUCE: Create a PDF document with the character U+006D LATIN SMALL LETTER M
 in Linux Biolinum O, for example with libreoffice.

Expected behavior: The 'm' is displayed

Actual behavior: The 'm' is not displayed (but does take up space)

This issue is discussed in this thread in the poppler forum, which leads me to think it is a problem with the font: https://lists.nongnu.org/archive/html/freetype-devel/2018-12/msg00063.html
