Emoji decode when recieve a message

[Terrorhawk]

Does anyone know how to filter the emoji in a recieving message?

i'm creating a messageboard with this api to display recieved messages on a big screen. but the problem is that i get those special char that supose to be a emoji.
does anyone have a function so that i can filter them out and display a emoij from a gif file (css or so)?

I already have the codes and the full size sprite image, just need a clone of myself to make some time to implement this..

$emojis = array(
                        "‼",
                        "⁉",
                        "ℹ",
                        "↔",
                        "↕",
                        "↩",
                        "↪",
                        "⌚",
                        "⌛",
                        ...
                        "\ud83d\udeb4",
                        "\ud83d\udeb5",
                        "\ud83d\udeb7",
                        "\ud83d\udeb8",
                        "\ud83d\udebf",
                        "\ud83d\udec1",
                        "\ud83d\udec2",
                        "\ud83d\udec3",
                        "\ud83d\udec4",
                        "\ud83d\udec5"
}

I'm on my phone at the moment so I can't tell correctly but is that the full emoji sprite you're using @shirioko?

If so I think you're missing loads of them. Check out my last commits to get another sprite. Hope that helps.

I think so too, I remember having a lot more emojis on my Android device than on WP7 which I'm using right now.

i think its per device.

Here is a link to the emoji of ios6

The emoji are actually part of the unicode standard, although most platforms only support a small selection of them (https://en.wikipedia.org/wiki/Emoji).
You can easily extract all .png files (48x48 px) from the WhatsApp apk, their filename corresponds to the character code (e.g. e537.png). The only problem is copyright stuff...

what i dont get is:

i recieve this (well it printen in the shell) �

this sould be the pile of poo emoji (1F4A9)
But how to get from those 2 chart to that Unified code ?

Encodings. Unicode is often represented as UTF-8. In plain old ascii, every byte was a character. However, to support more than 255 characters, UTF-8 was introduced which combines multiple bytes into a single character.
If you take a string (which is nothing more than a bunch of bytes) and apply the wrong encoding, such as any ASCII based encoding (latin-1, ISO-8859-1) instead of UTF-8, you'll see every byte as an individual character.

The 'pile of poo' emoji has the code e05a here (python interactive session for demonstration):

>>> u""
u'\ue05a'
>>> u"".encode('utf-8')
'\xee\x81\x9a'
>>> print "\xee"
î
>>> print "\x81"
 (note: this seems to be an invalid character)
>>> print "\x9a"
š

And when I look up e05a.png (extracted from apk) it is the pile of poo as expected.
Anyway, you should use the correct encoding, but I have absolutely no idea how PHP works with that. If you see those characters in your browser the page should be set to utf-8 too, I think... I tend to avoid PHP and webdev as much as possible ;)
