That is important as since you are the only person who has so far reported the problem, it will probably be hard for them to reproduce.

As I have already stated, I mentioned this problem just in case it was a known bug with a work around.

Anyone with any in depth experience of software development would look at the description of the problem paying particular attention to the worked then didn't work aspect and, noting that it was a one off, would have surmised that it was a random corruption somewhere along the line.

Which is why I said I was going to wait for the new firmware and start from scratch. Which would have worked perfectly.

Had I reported it to Kobo I would not for one minute expect them to try and solve the problem. I would expect them to suggest exactly what I was intending to do. It would be the only sensible response.

All this is why I asked the questions about the font files. I wanted to know if they were put onto the device in the manner the firmware expects. I wanted to know if they were still there. And all you can do is state that they worked before, they work under Windows, that you know more about fonts the rest of us (I'm perfectly willing to concede that), that you know more about software development than the rest of us, and in particular me (I've expressed my opinion on that) and that because things work in a particular way elsewhere, they must work the same on the Kobo devices. What you have not done is to is try and work out what is actually going on.

The fact that they worked before is extremely important and your failure to grasp that is what made me think you had little understanding of fault diagnosis.

As explained above, given that and the fact that this is NOT a known problem, I assumed corruption and that some level of system refresh would solve the problem - which it did. As it happened it did not even need the factory reset.

I certainly wasn't going to waste time attempting to diagnose something which I had come to believe was caused by some corruption.

Now, while I have been slowly typing this, I see that you have finally tried replacing the font files, and, no surprise to me, things are working properly.

Yes. Note: replaced the font files. Not renamed the font files. Not fiddled around with settings.

IF you were trying to be helpful, and IF it is no surprise to you, why did you not suggest simply replacing the files?

The only reason I didn't do it earlier was because I wasn't that bothered. And the fact that I had to spend so much time trying to get it through some apparently very dense skulls that the fact that the fonts initially worked meant that file names and parameter setting were virtually certainly not the problem in this case.

Of course, you have decided that it's something in the software and not a fault in the font files. I

It was virtually certain it was something in the software, because files do not generally corrupt themselves. At least, not unless there is some hardware failure, which didn't seem to be the case here.

But, I'll repeat my earlier plea: Please do not use calibre with your Kobo device.

Too late, sunshine.

That's how I've loaded about 20 books onto the Kobo with 100% success.
