Unicode block ranges vs Adobe Latin character sets vs RF Font Info Sheet OS/2 Table

[GregThompson]

I'm wanting to better understand the relationships between Unicode Groups and Block Ranges, The Adobe Latin character sets (Latin-1, etc), and the settings in RF Font Info > OS/2 Table > ulUnicodeRange and ulCodePageRange.

Is there a best resource that ties all this together?
This subject has been opaque to me for 30 years.

thank you

the OT specification is the the best resource.
