Superscript and subscript notations in dropdown fields

[JR Boulay]

I would need to put raw chemistry formulas in dropdown lists or values in scientific notation, it is therefore necessary for these two notations to access the superscript and subscript notations.

CH₄ is not CH4 and even worse when writing 1.7.10³ and 1.7.103!

Are there escape characters or encodings for the items in the dropdown fields?

Thank you.

Yes, this is possible to do in a text field, but you have to set it first as having Rich Text Formatting (under its Properties, Options tab).

Once you've done that you can enter the text as normal and then change it to super- (or sub-)script by pressing Ctrl+E, selecting the text you want to modify and clicking the relevant buttons in the floating toolbar that will appear, called "Form Field Text Properties". It should look like this:

Sorry, just saw you were referring to drop-down fields... In that case the answer I provided above doesn't apply.

What you can do is use the special unicode characters for those symbols, but then you are limited to just those, of course.

For example, this is the SUPERSCRIPT THREE character: ³

Thank you!

I will try that.

May be not possible.

Subsidiary question: should it be possible to use Unicode caracters in a JavaScript popup menu?

[try67]

Yes. You just need to find their correct code.

For the example I provided above it's "\u00B3".

Mille mercis !

I just tried but it does not seem to work.

JavaScript popup menu only displays superscript 2 and 3, unlike the dropdown field that is OK.

See this file with two menus, filed as same: https://documentcloud.adobe.com/link/track?uri=urn%3Aaaid%3Ascds%3AUS%3A5476bc75-3516-422f-badc-32ae...

You'll notice that the SUPERSCRIPT SIX character, for example, belongs to a different "block" than the TWO or THREE versions (Superscripts and Subscripts vs. Latin-1 Supplement). My guess is the latter is supported by the font used for the pop-up menu, while the latter is not.

[JR Boulay]

Both fields uses the same standard font:

That's not the issue. The issue is the font used in the pop-up menu itself.
