There are different things to consider:
- ADE 2.0+ (more precisely RMDSK 9.2 and beyond) display correctly the nnbsp whatever may be the font. This applies to a lot of ebook-readers like Kobo. InDesign does the same.
- For ebook-readers who do not display it automatically, you need to embed a font supporting it. It's true that few fonts include it, among them Linux Libertine and Charis SIL. Most Adobe or Microsoft fonts, (and also Literata) do not.
- However, one can easily add this character to any font using FontForge.
- Apple (iBooks at least) requires on top of this, a special line in META-INF to enable embedded fonts...
It's tricky but possible.
