IMO.
Sure, but I bet one symbol will emerge eventually. It just makes sense to use the most recognized symbol in your stuff which makes it more used and thus more recognized until one is the "actual" symbol and one is at best, the "old" symbol. Just a feeling about what will happen, not a should or an ought.
both symbols can evemrge/advance in different areas/purposes, like doen with others symbols/icons.
for example, you symbol more suitable for use in public area, ie as street mark/poster, while 1st variant is more suitable for docflow usage/mass-media ads.
or vice versa.
where is it actually matter is UTF table proposed change/update.
