No, it has to do with your denial that the Aura One software is very buggy.

Since 'very buggy' would generally be a somewhat relative statement I simply pointed out that I was relating the Kobo to the Kindle, of which I have had several, and on which the only bug I have found if that the reading speed is wrong and inconsistent to a bizarre extent. On the Kobo, however, I can cite a long list of bugs the I have personally found, leading me to the conclusion that this software is buggy and 'unfinished'.

Or possibly they were not "properly" used but just looked like they were.

That's gobbledegook in this context. The Kobo rendered two books perfectly well using Bookerly correctly. Then it refused to use the Bookerly regular font and rendered everything in Bookerly bold.

And as it is unlikely that the Kobo device shares code with any Windows application, and probably loads and uses the fonts in other ways, then whether it works elsewhere is only important in demonstrating the fonts are probably valid.

Correct. The fonts are valid. The Kobo is just not handling them correctly.

Really, not application that cares about file names? That's BS. I have plenty of applications that care about the file names they are using. Anything that uses a DLL cares. Or the various configuration files.

Sorry, I didn't realise how little you know about software.

Yes, of course individual files have significant names. What no decent software does is try and tie multiple instance header containing file contents with their names. There is absolutely no point in doing that. The name of the typeface is the name in the header file.

Sorry, is the font working or not? Is it working for one of those books or not?

"Well, yes, the format is obviously important, but it's well defined and the files work perfectly well in Window's application. They also worked perfectly well for two books on the KOBO. Indeed, one of them still works, it's just that it's picking the wrong weight."

Your phrasing doesn't tell me whether the font is working but wit the wrong weight for all books, or for one of the books it initially worked on.

"Secondly, it seems to have 'lost' a font. I loaded Bookerly, and used it quite happily to read a couple of books, then, when I started the next, the whole thing displayed in bold. I assumed it was a problem with the book, and soldiered on, but when I finished it, I discovered that all books displayed in bold only, and had to change typeface to get a normal weight."

As you seem to be having problems, let me guide you through it in simple steps. Then you may understand why I am all but certain it is not a problem with the font files:

1) USB loaded fonts onto Kobo
2) Ejected Kobo
3) Kobo says it is processing
4) New fonts appeared correctly
5) Read two books with new font with no problems whatsoever
6) Without any intervening connection to a computer, started a new book
7) New book displayed in bold
8) All books, including the two I had already successfully read now display in bold.
9) Did a hard restart
10 ) Problem remained.
11) Deleted one of the books I'd read successfully.
12) Current situation, ALL books display in bold when using Bookerly. (To spell it out, yes, that includes the one that initially displayed correctly.)

As I don't have access to the source code, I have no real idea what the firmware is doing between books. I do know it is updating the database in several ways, it's closing the first book and hopefully clearing memory properly, it's showing you the list of books that you might want to read which means it is either reading the cover image from the "disk" or the cache or generating them (depends on the book type, whether they are on the disk, or in the cache), formatting the list for you, opening the book, formatting the new book...

Should I go on?

No, because all you are doing is demonstrating that you don't really understand the intricacies of a file system - or where the file system is used and where main memory is used.
