This may be off-topic for this forum, but I thought someone here might know the answer to this question.
InDesign groups fonts by script in its Font Menu, but it's unclear to me exactly which criteria it uses for deciding which script block it decides to place a font in. Some fonts show up in unexpected places and I'm wondering exactly how it decides on this.
A few examples: Arial Unicode gets grouped with Japanese which isn't where I would expect to find it. A particular strange example is Astrology Pi LT Std where it splits the family in two, with Astrology Pi LT Std 1 showing up in the Latin block and Astrology Pi LT Std 2 shows up in the emoji block (both fonts have their characters mapped to the PUA block).
Poking around inside the fonts has been entirely unrevealing.
