I suppose if we get into the question of copyright you could ask my permission for you to use my "table" image before deciding to copyright your response to it.
Copyright is only for original works. You copied glyphs out of other works, which is not original. Alphabets are also not "original" (unless you designed it yourself) and in most places not copyrightable.
You could claim that the way you arranged them as a chart was original. You had to select appropriate ones and organize them. That might qualify for what they call a "compilation copyright" (similar to the way a dictionary is copyrighted—it's the arrangement of the information, not the information itself that is original). Only a legal system could decide whether there was sufficient originality in the arrangement to qualify for a compilation copyright. This is based partly on proportion and partly on how easy it would be for others to replicate it independently, but it is something decided by judges and lawyers, not lay people.
I used your table for scholarly/editorial noncommercial purposes and did not distribute it outside of the forum. That falls under Fair Use guidelines.
