Text -> Zap Gremlins… should work, though depending on the content it may remove more than just the emojis.

Tim,

BBEdit is PCRE2 16-bit based so maybe a unicode regular expression can help you. But Unicode is tricky and defining what applies as an emoji depends on many factors and possible combinations.

This regular expression seems to catch many emoticons, emojis, etc. but I don't know if it is exhaustive.

At least it seems to work in BBEdit and can be modulated to select specific Unicode blocks.

```

|[\N{U+1F000}-\N{U+1F02F}] (?# Mahjong Tiles 44)

Thanks all for the quick and informative responses . The "Text -> Zap Gremlin" of Rod did the trick!

Be careful, when you are dealing with a UTF-8 document, this may zap more tan you want.

Forexample, I often use ¹ and ² in documents and simply removing them will cause the footnotes in the text to lose their context.

There are, of course, many other UTF-8 characters that may be zapped, including ñ and √ and ç that may cause problems if removed.

If you change 2√x to 2/x by zapping, that could be very bad.
