UTS#51 and emoji-sequences.txt

[Yifán Wáng via Unicode]

Hi,

Sorry for delayed reply. The reason I posted here was that I wasn't
sure how it was intended to become. Do you have an idea whether I can
trust actual type_field value of each row over the description in the
current txt file?

Thanks,

Wang Yifan
