Re: Counting Codepoints

Any system that exposes Unicode strings (not UTF-16 strings) cannot have two surrogates merge when two strings are appended. There's nothing in the Unicode standard that says that should happen for a string in an arbitrary format, and it's unreasonable behavior for a string. Thus a Unicode string

RE: Rights to the Emoji

Exactly: specific designs are subject to license terms determined by the original designer, which are liberal in some cases and not in others. But the concept of a such-and-such emoji and it's encoded representation are not an issue. Peter -Original Message- From: Unicode [mailto:unic

Re: Counting Codepoints

Replace U+FFFE by U+FFFD in my message (but there are applications that also prefer using non-characters for those replacements, this is also an additional alternative, as U+FFFE has a valid representation as well in UTF-16). U+FFFD is not the only possible replacement even if it is recommended (by

I would contact Apple about it. Many Ads on TV etc... are using this Emoji set. So there must be a way to get access, or they do not care. Thanks, Niki Selken Working on: www.nikiselken.com On Mon, Oct 12, 2015 at 10:07 AM, S

Twemoji are Open Source, but published under CC-BY and that license requires attribution which might be challenging in this specific use case. On Oct 11, 2015 10:46 PM, "Mark Davis ☕️" wrote: > The twitter images are open sourced, I believe. > > {phone} > On Oct 12, 2015 02:56, "Shervin Afshar"

Re: Counting Codepoints

I agree with Ken on "Any discussion about properties for surrogate code points is a matter of designing graceful API fallback for instances which have to deal with ill-formed strings and do *something*.", and here's be my advice based on that. You want the code point count to reflect the same coun

Re: How can my research become implemented in a standardized manner?

This proposal is, in my opinion, similar to another discussion about giving unicode character to food allergy symbol that happened few months ago on this mailing list, which both idea want to use unicode characters to overcome language barrier, just that that proposal were about those icon while th
