Obisidian has decided that a comma is a separator even when it is within quotation marks. So entering “O Brother, Where Art Thou?” as an alias means that you will end up with two aliases: “O Brother” and “Where Art Thou?”.
But one of the reasons we use quotation marks is precisely to keep a phrase together, or to take into account punctuation marks within a phrase.
I can understand wanting ease of input, and using a comma as a separator, but not when it is within quotation marks!
This breach of yaml standards breaks my vault. I have nearly 2.000 files in need of manual revision because the analysis of the translated title stored as aliases is important.
