Can't have single number when adding custom time signature

ALT+0216 deals with my first symbol, but it gets a denominator. I can't get a space into the denominator box.
I'm using Windows 10.

What is a time signature of a single number expected to mean?

But what does it mean? To be honest, I often use musescore to get rid of unclear notation like this.

I now know that it can be done in MS3. Don't use Time Signature Properties, but create a signature under Master Palette, where a space can be put in the denominator field. Other special characters can be entered if you know the keyboard or ALT code.

Here is a snippet from the facsimile of Susato's Danserye (1551).

And here is how I represent it in my "urtext" edition - see www.johnkilpatrick.co.uk/music/Danserye/

If you view the .mscz version in MS2 it will look right, but in MS3 the unusual time signatures don't load correctly (and maybe some other features). The reason I have used MuseScore is that anyone can download it and learn to use it, and is thereby free to use my edition as they wish, including modernising clefs, times, etc., and transposing to suit various instruments.

Um, yes, this was what confused me when I was doing https://github.com/musescore/MuseScore/pull/5313. Perhaps the cause is line 302-303 in timesig.cpp, if I have time later I can test it.

~~Actually if I remember this correctly the empty denominator isn't replaced by 4 -- it's replaced by the denominator figure in the previous time signature. Say if you have a 3/8 before then the following empty denominator is replaced by 8.~~ (musescore.org doesn't support strikethrough?? see #295271: Writing on musescore.org doesn't support strikethrough)

EDIT: I was wrong, see the commit message for https://github.com/musescore/MuseScore/pull/5370/commits/c583d8ca9cfac4….

See https://github.com/musescore/MuseScore/pull/5370.
I noticed if the numerator string is empty and denominator string is not, the denominator string gets placed at the bottom of the clef, not at the middle. I don't know if that's an issue, but whatever it is, I don't think it needs to be taken care of by this particular PR.

If there is only 1 number it needs to be centered or allowing only 1 number to be displayed is not very useful, though you can move the number manually.

This is still a different issue, isn't it?

Not in my opinion. Allowing only a denominator to be shown where people don't expect it is only a half fix.

OK, fixed.

The complete fix is in https://github.com/musescore/MuseScore/pull/5370, but https://github.com/musescore/MuseScore/pull/5315 also fixes a part of it, only for the case when numeratorString is empty.

The problem the latter PR wanted to fix was not this one, I just assumed it fixed it too. Turns out I was wrong.

So #308139: Time signatures created pre-3.5 need special handling to avoid unintended loss of denominator is a duplicate of this one.

Oh yeah. So I was mistaken this time and not that time.
