This is, largely, aimed at Stephen MacLean . . .

Code: Select all

on mouseUp
   put empty into fld "f2"
   repeat until char 1 of fld "f1" is empty
   put codePointToNum(char 1 of fld "f1") into NUMMER
   if NUMMER > 128511 then
         --do nix
      else
         put numToCodePoint(NUMMER) after fld "f2"
      end if
      delete char 1 of fld "f1"

Hello Richmond. I've been fooling about with your emoji stripping stack. I have found that emojis cause the <open printing to pdf> command to fail silently. Being able to strip emojis would be helpful for that as well.
Using codePointToNum(tEmojiChar) > 128511 doesn't seem to catch all the emoji characters...
this cat head < 🐱 > returns "128049"

Also some emojis now have multiple skin colors < 🧜‍♂️🧜🏾‍♂️ >and that seems to throw a monkeywrench into the works, too. When I view this post in a browser, I see that the second merman is followed by a <brown swatch> and then a <male sign>. However, the second merman I pasted was actually slightly browner than the first (and looked correct when it was originally pasted) but does not seem to pass through the posting mechanism correctly. The brown swatch and male symbol seem to be incorrectly parsed away from the second merman.

Hi Richmond,

Thanks for posting this!

There are multiple ranges for emojis, as more were added in each version on Unicode.

Here is the list for the latest version of unicode 12.0

https://www.unicode.org/Public/emoji/12 ... i-data.txt

I think that between your stripper and updated unicode map, it should be able to find and strip them all?

I guess I'm a terrible snob, but I cannot understand why the Unicode consortium
are dragging themselves through the mud with their Emoji Obsession when they
should be concerning themselves with writing systems.

On a slightly tangential note:

This:

Code: Select all

if NUMMER > 128511 then
is just fine,
but this:

Code: Select all

if NUMMER > 128511 and < 130000 then
throws a "bluey".

Can anyone teach me some basic Logic?

Code: Select all

if NUMMER > 128511 and NUMMER < 130000 then 
It might be easier to visualise if each case to resolve as true/false is parenthesised so you can see what the operator is comparing

Code: Select all

if (NUMMER > 128511) and (NUMMER < 130000) then

Livecode can do this far far more easily than:
