How to find a textual description of emoticons, unicode characters and emoji in a string (python, perl)? [closed]

问题

The detection and counting of emoticon icons has been addressed previously.

As a follow-up on this question and the solution provided, I'd like extend it with ability to link the detected emoticons, unicode characters and emoji to their corresponding (textual) descriptions:

emoticons (Western and Eastern, e.g. List_of_emoticons from Wikipedia),
unicode characters (e.g. U1F600.pdf available from the unicode website (direct link is included in the previous stackoverflow question mentioned above),
other emoji types, e.g. from the list of emoji frequently used in Twitter (twitter-emoji-list from the emojipedia website).

Is there any comprehensive solution already available for conducting such a translation, in python or perl, similar to the method implemented in Swift? If not, can you make a script that provides a textual description for an emoticon/emoji found in a string?

perl example using charnames:

use 5.014;
use strict;
use warnings;
use utf8;
use open qw(:std :utf8);
use charnames ':full';

my @faces = split //, '😄😀😈';
for (@faces) {
    say sprintf "U+%05X %s %s",
        ord($_), $_, charnames::viacode(ord($_));
}

prints

U+1F604 😄 SMILING FACE WITH OPEN MOUTH AND SMILING EYES
U+1F600 😀 GRINNING FACE
U+1F608 😈 SMILING FACE WITH HORNS

回答2:

Python has the unicodedata import module with data on all the Unicode characters:

import unicodedata as ud
s = '\U0001F604\U0001F600\U0001F608'
for c in s:
    print('{} U+{:5X} {}'.format(c,ord(c),ud.name(c)))

Output:

😄 U+1F604 SMILING FACE WITH OPEN MOUTH AND SMILING EYES
😀 U+1F600 GRINNING FACE
😈 U+1F608 SMILING FACE WITH HORNS
