I seem to have a text formatting issue in some CoC modules but not others. I noticed it particularly while reading through Doors to Darkness and then went looking for it in other areas. The problem seems that whatever font is used in certain sections doesn't like apostrophes and em dashes (maybe others) and replaces them with block characters. The problem appears in the Ruleset scenarios and misc. text but not in the Reference Manual section of the module. It also appears throughout the aforementioned Doorways to Darkness. It doesn't appear in the 2 other modules I have purchased, The Investigator's Handbook and Alone Against the Dark. Also, the issue only appears in FGU and not FGC. Please see attached screenshots.
