Missing fonts - Characters shown as unicode boxes

2.10.14 for Mac OS

I have discovered that in the most current download - 2.10.14 version - for Mac OS - many of the Fonts are no longer available as they were in the former versions. For example Mistral and Curlz MT, which in particular I used often in the past, are showing strange symbols instead of the appropriate lettering in the text tool listing and in text boxes I create on images. Can these Fonts be recovered and if so how can I do that? Thank you for your kind attention and response regarding this disconcerting snafu. Attached is a screenshot illustration of what happens when for example I try to use the Mistral font.! Screen_Shot_of_Mistral_Font
