Thanks. I’d need to know _at least something_ about what the characters signify, though, to have a sense of whether there’s anything potentially offensive.

One approach would be to find a non-gibberish text string using some Plane 2 characters and add the BMP glyphs to the font mapped to the BMP PUA. Because if only a handful of BMP CJK glyphs were added to the font mapped to their standard code points, the font might need to claim to support BMP CJK (when in fact it does not) in order to display the sample text. Or, (if standard code points are used) the font might be auto-detected as supporting BMP CJK by some applications, when it doesn't really support that range.
