Are you using the system or the FM character map?
Anyway, I just tried this in FM9 on Win7/64.
The 21E7 code point is not populated in "Arial", although simple Arial does seem to have numerous Unicode glpyhs. I had expected it to be the same old Western 1252 set, but MS has apparently extended it somewhat.
21E7 is populated in "Arial Unicode MS", and pastes into FM with no problem, as an "UPWARDS WHITE ARROW". If I change the font to Arial, it reverts to a "?".
If I were going to use this in a document, I'd be tempted to implement it as a Variable, so that the font assignment is deliberate, sticky and ends after the glyph.
Font Family Arial Unicode MS (everything else As-Is)
When I run this experiment in Wordpad, I get a similar result; a "no glyph" box when Arial is applied to the U+21E7 character.
If I save that setup as RTF, and open it in MS Word, on the other hand, Word silently converts the missing glyph's font to "Cambria Math", and shows an outlined up arrow. This is all-to-typical "Bill Gates is smarter than you are" MS behavior. I haven't checked to see if one can drill down into a menu that would turn this feature off.
Thanks for the assorted tips – I beat the problem into submission by going for Arial Unicode MS and a character style. When the FM character palette offers visible characters for U+2423 and U+21E7 in Arial it's clearly being optimistic … or using some sort of hard-coded list instead of reading the font from the PC.
1. Search for "Upwards arrow" on this site:
Typing Alt +2191 does not work, so proceed with the next steps.
2. In Windows Character Map, go to Unicode 2191.
3. Copy the character and paste it in FrameMaker.
This always works for me, even in DITA XML and HTML.

There's a registry hack to enable that, and other alternatives.
Here's a typical resource:
Hello, Yves – I've found when mixing Windows and Frame that I get irritating messages about MS Shell Dlg [or something like that], so I tend to avoid it. fileformat.info is a great resource for checking unicode values, though; I've used it many times, probably most often when updating my harmonium scores wiki from a W*ws PC or a Mac instead of its native Linux …
