How to find Emoji by grep?

Question

Hey Grep-Experts and Emoji-Lovers,i imported a text from a pdf coming with some characters in Apple Color Emoji. After reformatting the whole text I now want to assign a character-style to all Emojis again.I can find e.g. with s/r like <01F525> (if i copy/paste the invisible character into s/r), but I cant get all the Emojis, using a grep like <.+>Does anyone know to find and format these reformatted emoji font?

No need to list them all. The GREP notation supports ranges:

[\x{1f600}-\x{1fb00}]

where the end value is eyeballed, more or less, because (1) Unicode.org keeps on adding more emoji (instead of, let's say, more useful symbols as those for rare alphabets) and (2) of course you still have to have a font that contains those emojii.

The <> notation actually denotes the unicode of the character that is to be searched, the number in between <> is the unicode value of the character and that reamins the same irrespective of the font/formatting applied over the character. Now when you find a character you need to know what character it is, in your case you need to know the unicode of the characters that denote the emojis that you use.

If you want an automated solution that finds the emojis in your text then you will have to identify the unicode values that denotes the emojis that you use and then use it in your search string, and use something like

\x{01F525}|\x{01F526}
