Following the note in the PDF Reader docs:

I notice that Zotero seems to require that the "page" numbers in links be numeric, specifically Arabic numerals. For example this works great:

zotero://open-pdf/library/items/TU7EY5ZW?page=4

But if I use something like "IV" instead of "4", it doesn't work.

I'm on a Mac and these links open for me in Preview where the page reference causes the "Go to" dialog to open and then sees the page number typed in it. When the number isn't a number, then I can see a "NaN" go in there, which of course doesn't work.

The issue is that these aren't actually page numbers, but page labels, at least the way Preview works. So if there are page labels that are Arabic numbers (as often the case), this is all well and good, but if there are labels that are not Arabic numerals, no dice. This is an uncommon scenario for me, but it does happen.

Am I missing something?

(Couldn't find the API info on this.)

TIA.
