Footnote reference disappears when adding Unicode 1D513 into line
I am using InDesign 14.0.2.
We are a book publisher, and we sometimes use a special character in some of our academic work: a gothic P—the Unicode character 1D513 (Mathematical Fraktur Capital P). See: https://www.fileformat.info/info/unicode/char/1d513/index.htm
However, it does something very wonky with footnotes, which seems to be a bug. If we insert this character—Unicode 1D513—in the same line as a footnote reference, it makes the footnote reference disappear. The footnote stays in place. We have tried different fonts, but it doesn't seem to be font dependent. However, if it is in the same line, but after the footnote reference, it still appears. So it seems to be some strange interplay of this unicode character and the footnote references.
I don’t know if there are any other characters that do this, but it doesn’t seem to be font dependent. The only way we are able to make the footnote reappear is to make the paragraph use the Adobe Paragraph Composer, instead of the Adobe World-Ready Paragraph Composer. However, this too is a problem because the paragraphs that use this particular Unicode character often have other languages in them as well, such as Hebrew, and we need the World-Ready Paragraph composer on to make those work, so we can’t just switch that so easily.
See the attached InDesign document for an example of what happens. You’ll notice the special character P is right before the second footnote, but it is completely invisible, while still being “there.”
I don’t know if this bug goes beyond this particular Unicode character or not, but it seems strange that InDesign footnotes are not playing well with it.
Thanks for your help.
I have an InDesign file if you need a sample, but the uploaded won't let me attach it. Can I email it to someone?
This issue has been fixed in InDesign 2020. Please try this out.
