A red cross should not be used

[maekawa-mugi]

A red cross is used in the hospital (U+1F3E5) and ambulance (U+1F691) emojis.
The Geneva Convention and Japanese law limit the use of the Red Cross to the Red Cross Society in principle.

Therefore, I propose that it should be changed to a blue asterisk instead.

*Supplement:
I made a mistake. The blue asterisk is the symbol used for ambulances.
Google and Apple appear to be addressing this issue by hollowing out the center.

I believe that a white background with horizontal and vertical lines is considered a red cross, and that changing the color of the cross or hollowing it out would work around the problem without destroying the impression.

Additional Info:
Mr. Shigeta (ex. Docomo), known as the father of the emoji, spoke about the hospital emoji on Twitter.
According to his story, the Red Cross pointed out that the emoji colors have been changed.
