Symptoms

On mac OS X 10.15 Catalina fonts are rendered wrongly (for example, all letters are replaced with 0) in export file after processing document with FineReader Engine 12 for Mac. 

Cause

Such behavior can occur because of Apple update. Now it is necessary to specify path to folder with fonts for FineReader Engine or install default fonts locally for user, which could be found in "/System/Library/Fonts/Supplemental". Both solutions are described below:

2. Font Book -> Preferences ->Default install location->Computer
3. Then, in toolbar press + or File->Add fonts
4. Choose folder "/System/Library/Fonts/Supplemental" and press Open
5. Fonts will install after the password.

Installing default fonts copy folder with fonts:

Copy fonts from "/System/Library/Fonts/Supplemental" to "/Library/Fonts"

Specify path to font's folder for FREngine:

 FREngine::customFontSet->put_Folder( L"/System/Library/Fonts/Supplemental" )
