What fonts have you tested? There are hundreds of thousands of fonts out there, but the ones that include a full set of superscripts are probably very much in the minority, with most of the rest only including ² and ³.

Serif WebPlus X8

Body text font is Verdana, and I've tried several others for superscripts, including Arial & Times New Roman & WingDings. All fonts I looked at had the same missing numbers (123) for superscripts [see image below]. Subscripts have a full set of numbers. I've been using superscripts from Arial for the last couple of years.

Is there a workaround to prevent WebPlus from adding space above the line to accommodate superscripts in "text, character, superscripts"? In the image below "Organic Energy" has a superscript from Arial a year or two ago, but "Physical Energy" has a new superscript added today.  Notice the extra linespace above the superscript "4".

That's strange. I've been using Arial superscripts via Font, Insert, Symbol, Other for several years. But the 1,2,3 superscripts have only recently disappeared from the table of symbols. Does that make sense to you?

Note : For convenience, I've retained all superscript numbers on the bottom line of the table. But as I add new symbols, the old ones get bumped off. Naively, I thought I could just add them back in, but discovered that the most common superscripts are missing from the current table. In my technical writing I use a lot of footnotes.

PS___ I've been using Arial superscripts instead of Verdana to make them small but noticeable and readable. Now the Verdana table of symbols is also missing the numbers 1,2,3.

That’s too big, of course, if it’s in a block of 8 or 9 point text! Generally speaking, superscripts and subscripts should be around 70% or 75% of the size of the body text.

Thanks for the tip. I had tried it before and found that it added a linespace above, which is the problem I was trying to avoid.  I work hard to make my HTML documents look like printed works. But the inherent HTML and WebPlus limitations make it almost impossible. Using the Insert/Symbol/Other worked well for several years, but now that option too is blocked by the missing 1,2,3 in the list of superscript symbols.

Alas, I continue my search for a superscript sans linespace.

PS___ I found that Unicode superscripts will work, but it's a lot of work to go outside WebPlus to copy & paste from these websites :

Apparently WebPlus X8 is not Unicode compliant. Any ideas for a Unicode shortcut or workaround?

I think you will find that the superscripts 1 2 3 are at the top of the page of symbols and the other numbers near the bottom.

The place to which you move them doesn’t have to be that ‘selected character’ line. You can simply insert the numbers into a text frame, and then move the frame to the pasteboard or the Assets tab.

I can’t reproduce the extra line space here, but looking more closely at the screenshot I can see that the superscript 4 after “Physical Energy” isn’t the same as the superscript 4 after “ideas”.

Thanks for your observation, Joe. I think you’re right, and that difference explains the issue which the OP has been struggling with. If I place the cursor in a block of text set in 36pt Arial and choose the ’Paragraph…’ option on the Text menu, the default line spacing is shown as 42.750 pt; if I do the same with a block of text set in 36pt Verdana, the default line spacing is shown as 44.250 pt. Changing the line spacing from ‘Single’ to ‘Exactly’ allows me to set the value to 42.750 pt, and the lines close up accordingly.
