CC's interpretation of NC is purposefully vague to be flexible: https://wiki.creativecommons.org/wiki/NonCommercial_interpretation
In my opinion, that doesn't make it very useful; NC is mostly a barrier to combining with other FOSS licenses, especially the big copyleft licenses.
In some cases, artists and musicians feel more comfortable with CC licensing... 1/2
But, back to your example - I think a reasonable interpretation would allow use of those emojis as "not primarily intended for or directed towards commercial advantage or monetary compensation.", which is the CC interpretation (though not actual legal advice, precedent, or ruling). 2/2
@ebel @rysiek @cwebber @Shamar @starbreaker interesting... attribution can be difficult for artistic works too, e.g. combining CC graphics from multiple sources for print works or merchandise (where do you put attribution on a one inch button?).
OSM should probably also ask the contributor to license any of their original work under ODbL when they submit; dual licenses would probably make life easier in the long run, but also new versions of CC licenses can address this compatibility directly.

"Where do you put the attribution?" Sec 3(a) of the CC-BY-SA licence covers this.
Copyright holder gets to define a "reasonable manner" (3.a.1.i)
#OSM has a form letter ( https://drive.google.com/file/d/0B3PN5zfbzThqeTdWR1l3SzJVcTg/view ) which asks the holder to agree that a mention on the osm.org/copyright page suffices.
Also CC licence forbids use with DRM (2.a.5.c), OSM licence allows it if you offer parallel download.
