[tex-live] fc-cache documentation ?

[Philip Taylor]

Apropos of this discussion, those members of this list who also subscribe to the XeTeX mailing list will know that a few days ago Apostolos Syropoulos asked for volunteers to test Frederika2016 :

> I am working on the digitization of Frederica Zapf (the Greek part of > Virtuosa Zapf) and I would like to know if there is anybody in this > list who would like to play a bit with font and give me some > feedback.

I volunteered, Apostolos sent me a copy of the font, I installed it, re-compiled the Catalogue of Greek MSS in LPL after changing the Greek font from Palatino Linotype to Frederika2016, reported that a couple of glyphs appeared to be missing (GREEK NUMERAL SIGN (Dexia keraia) and  GREEK LOWER NUMERAL SIGN (Aristeri keraia)) and that was that.

Today Apostolos sent me a new copy of the font, I installed it, re-compiled, and found the glyphs still missing; Apostolos said they were now present, sent test files to shew the missing glyphs were found on his system, then suggested that perhaps I was still using the old version of the font and sent a further version.  The new version also had no effect when installed.

Then he sent a test file that referenced the font as "[Frederika2016.otf]" rather than as "Frederika2016" as I had been using, and with that change I too could now typeset GREEK NUMERAL SIGN (Dexia keraia) and  GREEK LOWER NUMERAL SIGN (Aristeri keraia) using "[Frederika2016.otf]" but not if using "Frederika2016".

I then :
> deleted every instance of Frederika2016.otf I could find; deleted the font Frederika2016Italic from the Windows font directory; ran fc-cache; re-booted; deleted a single instance of Frederika2016 from the registry; and finally, in desperation, I deleted the entire contents of :
>
>     C:\TeX\Live\2016\texmf-var\fonts\cache
>
> When I next compiled Untitled-11, it re-created
>
>     C:\TeX\Live\2016\texmf-var\fonts\cache
>
> found (somewhere, I wot not where) a file "Frederika2016.otf" and a font "Frederika2016", compiled Untitled-11 without error, but (of course) had missing glyphs for the two number signs.  I have not the slightest idea what is going on.
Can any knowledgeable person please tell me how I can ask XeTeX/fontconfig where it is finding Frederika2016 ?
