Failing to match emoji keycap numbers 0-9, # and *

[rodrigopolo]

I tested, all emojis available on iOS 9.1 / OS X 10.11.1 and it is failing to detect emoji numbers:

\u0030\ufe0f\u20e3
\u0031\ufe0f\u20e3
\u0032\ufe0f\u20e3
\u0033\ufe0f\u20e3
\u0034\ufe0f\u20e3
\u0035\ufe0f\u20e3
\u0036\ufe0f\u20e3
\u0037\ufe0f\u20e3
\u0038\ufe0f\u20e3
\u0039\ufe0f\u20e3
\u0023\ufe0f\u20e3
\u002a\ufe0f\u20e3

As typed

0️⃣
1️⃣
2️⃣
3️⃣
4️⃣
5️⃣
6️⃣
7️⃣
8️⃣
9️⃣
#️⃣
*️⃣

👍 I noticed this as well, there are also ~70 emoji that can have a \uFE0F at the end, it's the emoji variation selector.

Or maybe it's at the beginning... Hard to tell when there are adjacent emoji.

Sorry, definitely supposed to be at the end: http://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.html

[rodrigopolo]

One thing is "supposed" and other is "in practice", Apple, Google and Microsoft implement Emojis very differently, that's why after a long process I decided to create a regex using all emojis typed from the vendor devices (removing any duplicate) then sorting them by length, the big one first for replacement, then if a match is found I strip all the extra emoji characters that don't do something relevant, like the variant selector and the other that glues together emojis, in this way I can find any emoji and find their unicode representation easily.

Sorry, I was only replying to my previous comment about \uFE0F appearing at the beginning or end of ~70 other emoji (in the non-keycap emoji it's supposed to be at the end), you are correct that it's supposed to be (and appears in practice) in the middle of the keycap emoji. :)

Hi,
I have a php function to remove the emoji, but how can I add these particular emoji in my function?

function remove_emoji($text){
  return preg_replace('/([0-9|#][\x{20E3}])|[\x{00ae}|\x{00a9}|\x{203C}|\x{2047}|\x{2048}|\x{2049}|\x{3030}|\x{303D}|\x{2139}|\x{2122}|\x{3297}|\x{3299}][\x{FE00}-\x{FEFF}]?|[\x{2190}-\x{21FF}][\x{FE00}-\x{FEFF}]?|[\x{2300}-\x{23FF}][\x{FE00}-\x{FEFF}]?|[\x{2460}-\x{24FF}][\x{FE00}-\x{FEFF}]?|[\x{25A0}-\x{25FF}][\x{FE00}-\x{FEFF}]?|[\x{2600}-\x{27BF}][\x{FE00}-\x{FEFF}]?|[\x{2900}-\x{297F}][\x{FE00}-\x{FEFF}]?|[\x{2B00}-\x{2BF0}][\x{FE00}-\x{FEFF}]?|[\x{1F000}-\x{1F6FF}][\x{FE00}-\x{FEFF}]?/u', '', $text);
}
