[UA-discuss] Fwd: Re: base1024 encoding using Unicode emojis

Mon Mar 12 18:47:16 UTC 2018

Dear Asmus,

Until the standards are not in place – yes, IETF, ICANN and bunch of other places, but UASG is not a place for that.

We don’t need to defend Chinese script or raise awareness on Chinese ideograms vs emoji. 

Personally, I am not happy with RFC on EAI, which is the main topic here, but I am not ready to discuss it here. Instead, I was debating with creators of relevant RFCs about my concerns. 

Therefore, I think it’s not a topic for us, not yet (if ever).

Cheers,

Dusan

The reason I forwarded the message below is that many people find something
familiar and  accessible about emoji and will not understand why there
should be more security concerns about them than about a bunch
of bewilderingly similar and complex Chinese ideographs or a bunch
of "dawn-of-time-emoji" aka Hieroglyphics, both of which are PVALID.

That means that some consciousness-raising needs to happen somewhere
and fast.

We generally think of emoji as a poor choice for reliable identifiers.

Which makes this discussion on the public unicode mailing list somewhat interesting.

Using emoji to help people verify security information is an interesting 
idea. What I'm afraid is that even if emoji are designed with 
distinctiveness in mind, some people may have difficulties distinguish 
all the various face variants. Also, while emoji get designed so that 
in-font distinguishability is high, the same may not apply across fonts 
(e.g. if one has to compare a printed version with a version on-screen).

Regards,   Martin.
