Sigil, HTML Tidy or PEBCAK?

[DTM]

I don't know if this is an issue with Sigil, HTML Tidy or (ahem) the user.

I created a book using Sigil, containing several chapters with xhtml filenames "1stDay.xhtml", "2ndDay.xhtml", ... , "30thDay.xhtml". I then created an "Index" chapter, containing numerous links to places within the other chapters. These included references such as: <a href="../Text/23rdDay.xhtml#PSM23">.

When I was done editing, I found that several links were broken. When I opened the book in Sigil to check on the code, I discovered that, randomly, the chapter references in the links were changed. For example, the above was changed to: <a href="../Text/3rdDay.xhtml#PSM23">. This didn't happen on all of the links, but when it did, in every case, the alteration was that the first digit in the chapter name was dropped. There are more details, but I'll save those for the issue report, if there is one.

I was able to fix it by inserting a letter at the beginning of each file name. Apparently, there is a problem with files that begin with numerals.

So here is the question: Does this look like a bug in Sigil for which I should open an issue, a problem with HTML Tidy that the Sigil folks can't do anything about, or is it simply forbidden to start an xhtml file name with a numeral (a rule I'm not aware of)?

I believe there is a requirement that filenames begin with a letter in epubs. Over in the ePub group, someone mentioned that Calibre also balks on beginning digits.
It seems that both Sigil and Calibre try and fix the problem.

This sounds like a bug. Try to make a repeatable test case and then head over to the issue tracker.

I use the following with no problems:

1-CHAPTER_IX.xhtml

indicating Part/Book 1 Chapter IX.

It's been workong fine so far.

OK, I'll take care of that shortly.
